Overall, it was a good stay. The host was very supportive and responsive (5 stars to her) - all our enquiries were dealt with very quickly (eg when we forgot the key inside). The only major issue was related to the AC. We booked this apartment specifically because AC was listed in the description (we knew July will be hot in Istanbul), however, when we came it was not installed (and this point was removed from the listing after we already made the booking). Nevertheless, this issue was resolved on the next day (the host installed AC in one of the rooms - not central though). To sum up, I think it's a good apartment but might be a bit uncomfortable in hot weathers. If you go, definitely, check the rooftop view
