The appartment is quite convenient and well located near taksim square.
We were a group of 5 people, the appartment was big enough and the 2 teraces are very nice to spend some time iutside.
we had a very good time in taylan appartment, and i recommend it.
Moreover, taylan is very reactive to help you or give some advice.
Good to know, the flat is at the 6th floor, without elevator, which can be sport when the temperature is high :)
