On our visit to Istanbul in August, we booked this apartment. It was in the same price range as other offerings, but at the same time close to the city center.
On our arrival, we noticed the following problems:
1) The apartment looks much bigger than on the photos. It is described for four guests, but in my opinion it fits two adult guests.
2) On the photos, there is a lot of light and the rooms look bright. In reality, the whole apartment is very dark. The light can't enter the apartment through the windows as shown on the photos, because there is a tall building in front which blocks entirely the sunlight.
3) The advertised photos of the apartment are professionally photoshopped / altered, so that the apartment looks bigger / brighter / newer than it actually is.
4) In the description, there are two beds, but there is only one bed and one couch.
5) The view outside the windows is a catastrophe. That is why there are no pictures of the view in the description.
6) The bakery, which is advertised as near the apartment, shares the same bedroom wall. The result is a hot wall which transmits so much heat that it turns the entire apartment into a sauna.
The sauna bedroom was for me a dealbreaker, as I could not rest or sleep at nights, and breathing was also difficult. In short, it was hot as hell.
We discussed this issue with our host, and he solved it very quickly by telling us that he was not in control of the weather or of his neighbors next door. At the end, he offered us to shorten our stay to three nights instead of a full refund.
I felt that this apartment was way overpriced for its shortcomings. I would not recommend this place even if it was a lot cheaper, as in summer it is uninhabitable.
