I travelled to Istanbul with my husband and our 4 year old daughter. Omer was great! We met him at a nearby cafe and he walked us right to the apartment. It was exactly as described in the listing, they even had a welcome present waiting for us! Everything was clean, the beds were confortable, there was heat, clean towels, we had what we needed in the kitchen and there were plenty of stores around if we needed anything besides what was provided.
Omer was available to answer all our questions, he recommended places to go and where to eat (great recos by the way)
We did not spend that much time in the apartment because there are so many great things to do around! We had a wonderful time and I would recommend to stay in Omer and Ozde place with my eyes closed.
