We were very pleased to stay in this flat, everything was good and met our expectations.
The flat is situated just 60 meters away from Istiklal street so you'll always feel the pulse of life in Istanbul.
The metro is just 200 metres away and the T1 tram is ~10 minutes by walk so all the transportation you need is easily reachable.
Some people mention the noise of the surrounding area and that is true, the area is quite noisy, especially on Friday and Saturday night, but I would say that the noise is not such a big deal and will anyway finish by 2 AM. Also, there is a door between the living room and the bedroom which you can close, and it will stop almost all the sounds that are coming from the streets, so you're covered.
