I wasn't hosted at the flat advertised, rather at the Pera Line Hotel (accurate photos can be found online). Bear this in mind if you count on cooking because the hotel has no cooking corner. I did not care about it though and was very happy with my stay at the Pera Line. Clean room, new furniture, clean bathroom, very nice and helpful staff. My only niggle was that it was a bit noisy till about 1 am.

The hotel was a very short walk from Taksim square with many shops, restaurants and bars around, also good transport connections.

I had a fantastic time in Istanbul and would recommend the hotel!
