This flat is in a great location. It is quite noisy at night-time, particularly one of the rooms, but I slept fine with earplugs in. The flat is large and has everything you would need. Beds were very comfy and the flat was very warm.
It is up 5 flights of stairs which was no problem for us. Great to be near the tower, shops and it is as easy walk to the other side (as long as you like walking!), if not a metro can take you there.
Nadira and Gokhan were both very helpful and informative throughout. Gokhan went out of his way to ensure a pleasant stay. I would recommend staying here
