Great! We liked it. When we came for check-in Selim made a tour of the apartment for us. After that he was online for any questions we had.
As for the location, it’s great too. We were going to see Hagia Sophie, Grand Bazar, Galata Tower, and we visited it almost everyday in different times! As well, you can find a grocery store nearby which works longer than other, it saved us couple times. And we enjoyed shops for artists nearby.
And we liked to come back to the apartment after a rich days. Thank you Selim!
