We chose this apartment based on the excellent reviews on AirBnB.... and had an excellent experience with this apartment in Istanbul!
The location is very central (ideally situated) but in a quiet street. The apartment is well decorated, confortable, spacious and clean.
In addition, Arva was a perfect host, always available when we needed him and with great restaurant tips. He provided us with an Istanbul transport card so that we didn't have to care about buying one. He also found a solution to provide us with a fast-speed internet access, although the internet provider had technical problems at the time we visited.
We definitely recommend this place for both the place and the excellent service.
