We had a pleasant experience staying here not just because it was a clean and cozy room with almost everything that we needed including the kitchen, also the staff, especially Ömer, were very helpful and easy to reach. The location is great and it's within walkable distance to Istiklal and metro stations (<10 mins). Also, there is almost no uphill/downhill to going to Istiklal street and way back.
Just note that there are ~20 stairs to go to the second floor and there is no elevator which wasn't an issue for us.
