The location is great! Flat is very light! It contains all equipment necessary for a long stay. We live there for 1.5 month and it was really comfortable to live there. Lino wasn't in Istanbul, but she responded to all our problems and questions very quick.
The one point that we didn't like, that the appartement wasn't well cleaned when we arrived. If improve that point that will be a really ideal appartement for a good stay in Istanbul.
