We were a group of 11 persons and spent 4 nights at Evin's location.
It is a charming place decorated with care. There are 3 bathrooms and an additionnal shower. There are 4 very comfortable double beds...so, it is easy for a group to stay here.
It is situated in a small street away from the noise and with nice restaurants around. It is 5 minutes walk from the Galata tower and you can reach all the interesting sites or public transports in 10 minutes.
But above all, Evin was very helpful in the preparation of our trip and very friendly. For sure, we will come back!
