I have stayed in various parts of Istanbul for at least one month stays and I must admit that this location and the place itself appealed to me the most.
As for the place itself, everything agrees with the photos, we have a very practical apartment at our disposal, a separate bedroom with a quite comfortable bed and a wardrobe, mega-equipped kitchen, definitely the most of all that I have had the opportunity to see so far, a shared living room with a comfortable rest area and tv.
In addition, access to the gym (admittedly quite poor in equipment, but for the needs of such a flat it is a plus, if someone uses the sauna is very nice, we were there every two days, anyway, as it is open.
Downstairs, at the entrance, security 24 / 7, you can go ahead and order food, there are many different options in the mobile application, besides, there are a lot of shops around.
As for the host itself, it is definitely one of the best I have met, communication 24/7, very nice and polite, I definitely recommend this place, you will not be disappointed.
