Nice hotel with hospitable and helping staff.
The room was warm thanks to the big air conditioner which could heat the room in 15 min. (we rent the room in the middle of December).
The room was clean, also it was cleaned by the staff during our stay.
Wifi sometimes was not working well - internet speed was low most of the time, but staff worked on this issue and in the end of our stay internet speed has become fine.
During our stay there was a lot of rains in Istanbul, host proposed free umbrellas which was very helpful.
Near the hotel (3 min walk) there are two restaurants with local cuisine with prices less than in other restaurants. The food there was delicious (one restaurant is "Begonville", another one - "Kebab House"). We spent a week in Instanbul and ate there only.
For those who will rent a room on the firtst (ground) floor, please notice that reception could be noisy sometimes (because of checking in/out guests I guess) and this noise is very audible in the room. We faced this only once, as it was December and there were not many guests.
In general, recommend this place for stay!
