The apartment is perfectly located - 15 minutes walking to Istiklyal, about 20 min to Galata Tower. The place is quiet and comfortable. You can hear only seagulls here, no cafe music or noise of the big city :)
The apartment is clean and bright. It provides everything for your comfort. We were really impressed with remote temperature control. Erhan set up comfortable temperature for us and we fogot about manual regulation. There is enough place for 4 people - 2 separate rooms have big beds with nice pillows, wardrobes, clean windows. The one room has a big working table wich was perfect for us. WIFI is fast and reliable. We made videocalls - everything worked perfect.
The kitchen is well equiped. Many dishes and cups, big frying pan. We liked to cook breakfasts there.
About the bathroom. We've read about smell issues before, that was reported by previous guests. During our stay at Istanbul the weather wasn't good - it was raining almost every day. But we left the bathroom window opened after taking a shower. No smell problems whatsoever.
And I must say several words about Erhan - our fantastic host! He speaks English very well, so he gave instructions before arriving - how to get to the apartment (gps location with photos of the street and the front door). Erhan told us about good places for eating, what to visit first and where we can book water trips. He was in contact with us during all our stay and offered his help in different questions. I strongly recommend not only this apartment, but this host. He is very hospitable!
