The flat is nice with all equipment you need for your staying.
It is very central and you can be in Galata tower just in a few minutes walks. Tram station is just a few meters from the flat as well the Tunel to go up to Istiklal street and ferry station Karakoy. Close from the appartment there are in more many good restaurants and cafe too.
Unfortunately, this central location has a bad side : appartment is quite noisy especially during Friday and Saturday night. Above all, neighbours don't care making noise during night time.
I would recommend it for couple or friends who like to enjoy night life but not for a family or people who want to rest.
