We are pretty sure you can't find this kind of quality for this price in all of Istanbul.
The service and facilities are top notch for such a cozy establishment. The staff is always helpful and willing to solve any problem or request that you may have. They speak english (you would expect that from every hotel but is not the case, believe me)
Specially David and Jacob, who were always trying to make our stay as comfortable and satisfying as possible. They are extremely friendly and professional. Thank you David for those delicious turkish coffees every morning!
Quite friendly and effective cleaning staff as well!
Also, very well located, just 5 minutes from Osmanbey metro station (from there you can explore all of Istanbul in their very efficient public transport service). The hotel is surrounded by restaurants, cafes, stores and other establishments.
In short, if you are looking for an affordable hotel without giving up cleanness, comfort and great service, Instanroom is the place to be.
