Large comfortable flat in a great location. Of course will be busy outside and with neighbours noisy til midnight. This did not bother us and we slept well.
There were cleanliness issues and broken item issues which host attended to once I raised it.
Rooms got warm, which was not a big issue for us but it might be hot in the summers.
Carrefour opposite for groceries and restaurants all around. Istiklal St and Taksim close.
Note first floor of stairs has no lift.
Place recommended and have given host tips to make it an excellent place.
