My wife and I spent a month in this apartment, and really enjoyed this place. Very central, and yet pretty quiet, no music or loud sounds at night. Spacious and very stylish place, very well equipped (washing machine, dishwasher, heating in every room, etc.). Big table + work desk. Good wi-fi.
Cagri is a great host, very attentive, and helpful. Super easy check-in and check-out.
You should consider, that apartment is located on the top floor. The stairs leading to it are pretty steep. Lifting suitcases up was a challenge, lifting ourselves every day - not so much :)
Bed could be softer and less creaky.
All in all, a great place to stay, definitely recommended.
