It was my first Airbnb trip and Zalal was very helpful - answered every other of my countless questions and arranged everything perfectly.
The apartment location m was outstanding: 5 minutes from Taksim square and main streets, 3 min down the street to embankment and the tram stop (from which you can easily get to Sultanahmet without any transfer) and a ferry station a bit further.
Flat itself is in attractive traditional style with small hints added by Zalal that makes it really cosy. You can see Bosphorus from terrace and it is also located really conveniently: on our stay the weather was awful first few days but even in strong wind you could freely sit in terrace. While inside you can control temperature with thermostat.
The only downside is a really steep staircase leading to the door but that is said in the description.
All in all, we really enjoyed our stay and would recommend renting it if you want to experience living like a local but also be able to visit all of the main attractions the city can offer.
