Family of 4. Stayed 1 night in a family room with private bathroom and it was perfect, even better than we thought. Very well located 10 min walk to the beach and 5 min walk to bus station to go to the city center. Would definitely recommend.

This is a hostel mainly for young proper as hostels usually are for. People coming in to the dormitory in the night talking and laughing loud. I was in a dormitory of 6 beds only for women. It was very small and the floor was crowded with big luggages even if there was a smaller box ( you need a locker) for your things.The bed was without curtain or anything like. The bathroom area was also very small. I have been to hostels more convenient than this one. And the price for one night was around 100 Euro!

Kontiki Tours and kids at a sport camp overwhelmed the hostel. Some staff were helpful, some moody. The beds offered little privacy, and the rooms were tight. The patio was unavailable for some reason - or reserved for the bus tour. The location is up a hill, but the parts with views have no chairs or social amenties.

The hostel had a privacy data leak and was used in a phishing scam. When I asked for a refund since I didn't trust them after my data was leaked, they refused. I booked a different hotel. Be careful booking with them.

We booked a complete room for 4 adults, immediately checked with hotel to make sure we had a private bathroom since we were traveling with my elderly parents, a private bathroom was all we cared about, they confirmed that the bathroom was inside but when checking in later that night, the bathroom was shared with other rooms and when we called to complain about it, they just said that the case was being reviewed but didn't answer until 72 hours later and they denied our claim. Not going back there and not recommending it to anyone with a family.

Nice quiet hostel
Really nice hostel. Clean and modern. Each bed has a lamp, plug sockets and a small space to store a couple of items. Stayed in the 8 bed dorm which was more spacious than the 6 bed dorm. Breakfast was basic - bread, cereal, tea, coffee, juice but included so can't complain.
Close to Ondretta beach (5 min walk) and 30 min walk to Old Town. Preferred Ondreatta beach as it was a bit quieter and sand better. A few places to eat and drink in the area as well.
Only thing that lets the hostel down is that there wasn't much of a social atmosphere. Mainly groups of friends and couples staying there and you would hardly see anyone at the bar. Still managed to meet a few people but not as social as I was expecting. Would be good if the hostel organised activities. So definitely not a party hostel but good if you want relaxed and chilled out.
Overall I'd say I enjoyed it.

A terrible check in process for anyone on the go
We were a group of 8 traveling together and walking the camino del Norte. This is on the other side of San Sebastián so added several km to an already long hike...in addition the check in process is the worst I've ever experienced. It took us 2 hours + as there is no person at the front desk to help. I was literally standing at an intercom with 7 others waiting for almost 2 hours! there has to be a more accessible way for those on the go to not have to enter every person' information. A front desk person would make this a much more pleasant experience. Otherwise it was miserable.

Viajé con mi mis dos hijos y estuvimos en una habitación con tres camas, que tiene un diseño que nos encantó. No tuvimos ningún problema con el baño compartido, y las áreas comunes son muy lindas. Nos gustó mucho el barrio, en Antiguo. Muy residencial y tranquilo. Hay que caminar algo para tomar el bus o llegar a zonas de Antiguo con restaurantes, pero a nosotros nos gustó la caminata. Está lejos del casco viejo pero en bus llegas a todo lado en San Sebastián. Este hospedaje está cerca de la PLaya Ondarreta, nuestra favorita, y del funicular que es un viaje muy lindo. Sería genial que en las duchas compartidas hubiera alguna división entre ducha y resto del baño para evitar que se moje el suelo de todo el baño. Hay una escobilla para recoger este exceso de agua, pero en nuestro caso algunas personas no la usaron “ a conciencia” y estaba un poco todo mojado a la hora usar el baño. Fuera de este detalle, los baños super bonitos y limpios.

bon compromis pour la semana grande

Estuvimos a gusto en general! Alojamiento tranquilo en la epoca que estuvimos, el personal muy atento y de rapida respuesta a las necesidades, nos pareció muy comodo tantos las camas como los espacios comunes y los baños. Solo pasamos una noche pero estuvo muy bien!!
Quizás reforzaría un poco la limpieza , se sentía pisar tierra /arena en la habitación. Gracias!

Il manquait les rideaux au niveau des lit qui était pourtant présent sur l'annonce et il y avait des traces d'usures au niveau des échelles (qui ne sont pas très pratiques d'ailleurs. Il serait bien également de préciser sur l'offre de séjour qu'il est nécessaire d'avoir un cadenas pour fermer le casier. Et pour les femmes, il serait plus rassurant d'avoir un verrou pour fermer la porte de douche.
Si on met à part c'est soucis/remarques, l'hôtel est situé dans une zone calme et facilement accessible à pied, le personnel est très réactif et aimable. J'ai passé un bon séjour.

Honteux
Il faut savoir qu'il n'y a pas de réception.
Hors je n'ai pas reçu par avance de leur part un SMS ou mail me permettant grâce à un code de m'enregistrer sur leur site afin d'avoir codes et n° de chambre.
Je suis arrivé à 20h et il n'y avait donc qu'un téléphone/interphone pour avoir de l'aide.Soit disant disponible 24/24 et 7j/7. J'ai du appuyer 50 fois pour obtenir quelqu'un. Qui parle bien sur espagnol et heureusement anglais. On était proche des 22h et je me voyais dormir dans ma voiture.
Enfin quelqu'un ! Le problème est que le son est nasillard plus le bruit de la cafétéria et des personnes présentes, c'était très dur de comprendre.
Entre temps, J'ai fait trois demande à Koisi hostel par internet sur leur site pour qu'il m'envoient un mail avec mes codes sans succès !!!
J'étais près de leur téléphone avec mon smartphone et mon PC portable durant tout ce temps.
Ce n'est que vers 22h que j'ai enfin pu faire mon enregistrement et aller dans ma chambre. C'est une honte un tel système et surtout qu'il n'y es aucune aide facile autre qu'un vieux téléphone pourri dans une pièce de passage. Sans réception de leur mail avec un code de réservation on ne peut rien faire.
A noter que j'ai vainement tenter par le numéro d'aide en 08 de joindre hôtel.com sans succès depuis l'espagne et j'ai fais toutes les combinaisons possibles !!!

Lo que necesitas para poder dormir en San Sebastian. Una de las opciones mas económicas. La habitación estaba muy bien. La cama cómoda. Lo único el baño compartido, no nos duchamos porque no habiamos llevado chanclas.
Por lo demás muy bien. Tiene un espacio con mesas y un microondas por si quieres cenar alli, y también tiene la cafeteria.
