Hatip was an excellent host, attentive but non intrusive. He was very helpful with our check in and check out, he even let us to keep the suitcases after the check out time, due to our after noon flight.
The apartment is very comfortable and well equipped. Everything was clean and welcoming.
The location is great, within walking distance to Haga Sofia, Blue Mosque or Topkapi Palace. The apartment has a small balcony that overlooks the street, where you can observe the local life of the restaurant owners or shops. This is a one way street, so the traffic and street noise are far less intense. I really recommend dining in the restaurants along the street, we were never dissapointed and the prices were reasonable. If you have time, I also recommend the Bosfor boat tour (ask Hatip), it really gives you a sense of how huge this city is.
Thank you Hatip for a wonderful Istanbul experience.
