Esra (the host) was beyond helpful and friendly. I arrived at 2am and she was on the phone with me throughout trying to make sure I got in and settled in ok. She was flexible and the apartment was just as described.
The apartment is in a prime location and is literally a 6-7min walk to Taksim square and 2mins walk to trams and all other public transport. The walk to Taksim is very hilly, which is quite common in Istanbul. If you have bad knees like me, this might be a challenge but Taxis and Ubers are very easy to get from the apartment.
The apartment has everything you could possibly need and the kitchen is VERY WELL stocked.
Bed is massive and floor heating was very useful especially during the winter.
Walls are a-bit thin so you may hear your neighbours but nothing that would stop you from a goods night rest.
I found the whole team (cleaner and doorman) very helpful and kind.
Will definitely stay again and HIGHLY recommend.
