Lovely place, lovely location, lovely host(s)!
We booked the aparment for 3 people and for 6 days. One of us wanted to stay a night longer and even though the airbnb system wouldn't let me book it, the host - Jannin - was so nice and managed it for us!
The aparment is very modern and nicely decorated and the location is unbeatable! Even my cousin, who's been living in Istanbul for over 5 years was blown away by the location of the aparment. It's in the heart of Kadiköy, supermarkets, restaurants, cafes, bars, places to shop... everything your heart could desire is within a radius of 200m.
The host itself doesn't live in Istanbul, but she has lovely friends who received us (very late because of problems at the airport, which was not a problem to them since we immediately called them and they were so nice navigating us via phonecall) and immediately offered us their help and told us to call them whenever we need to. Jannin was very kind and replied to all of my texts and questions very fast. She even managed to organize a brand new hair dryer for us!
Will definetly book this airbnb again if I'm in Istanbul again! :)
