Not great. The host was nice and welcoming, check-in was smooth. The apartment itself was fine and tastefully decorated, but the building smelled musty and did not seem sanitary. The neighborhood wasn't great either. We encountered two major problems: we got locked out of the building one time because I guess the door lock wasn't working properly and the shower was broken so we had to call the host to have it fixed. It took a few hours and of course having plumbers in the apartment trying to fix things while we were there was far from ideal. I have a house in İstanbul and booked this apartment because I'm having work done in my house, but unfortunately I didn't feel comfortable at all and decided to leave early and got a room in a hotel the next day.
