For me it was an excellent location, I was scheduled to be in downtown Cagliari the whole weekend and I could walk everywhere I wanted to from the apartment. Supermarkets, Restaurants, Downtown, the center of the city, sights, everything is near within normal walking distance.
Excellent free, fast and stable WIFI connection. Friendly staff and good service, clean rooms, not luxurious but very proper normal good sized room.
Very quiet despite lots of traffic outside, but I could hear the people in the connecting rooms, this is always the case anywhere and it can be a little annoying.
Highly recommended, for normalcy and good value I doubt you will find anything better, I will return on my next visit to Cagliari.
