We have been in Erdils place with 4 people. It‘s a tidy flat in the central of Beşiktaş. Everything inside the flat was very clean, the bathroom may be a little bit small. The check-in and the communication with Erdil were very easy. If you’re a light sleeper, the place where the flat is may be too loud as it’s a place where many pubs and clubs are.
All in all it’s a perfect place for a city trip, I would recommend it to all. It’s very easy to communicate with Erdil.
