The apartment is very well positioned, really close to Taksim Square, quite area, clean. We stayed for 4 nights, 3 adults, one 4y kid. Enough space for us.
Small changes neede there (toilet brush broken, wc lid keeps dropping on you when you sit on it), but these are just minor things, easy to be changed.
The apartment is really nice and warmly decorated, hosts really helpful, location amazing.
This was our second stay there, would totally go back there!
