Furkan is a great host - friendly, helpful and always quick to respond. The apartment is quite good - very clean and cozy, although a little different to how it comes across in the pictures. It's located right next to the 4.Levent metro station so it's very easy to get around. However the area itself is a bit of a mixed bag - it's a business district of sorts with not too much to do aside from shopping in one of the local malls. This is not a negative per se, depending on the goal of your trip, this might be just the right place for you. Overall, a good experience.
