I will write a very honest review of this place from my experience. I stayed for one week. Aesthetically the apartment is very beautiful, the location is great (7 min walk to İstiklal street and Taksim square) - there is a lot of shopping and restaurants on this street. Arzu was very responsive whenever I needed anything and a quick problem solver, which I really appreciated, she is a great host.
However, functionality wise it wasn’t the best. The WiFi is extremely slow, I could barely load pages on my phone. If you need to do any type of work while you’re there like I did I would not recommend it. The bed is also very uncomfortable. It is old, creaks a lot and ‘dips’ in the middle making it hard on ur back.
Overall, if you don’t need fast WiFi or care about the bed it is a good place to stay.
