I stayed in Selim's apartment for a week. It was a very pleasant experience. The apartment looks exactly as on the pictures, is very modern, clean and has everything I needed. Location is brilliant, only few meters from the heart of Taksim area and few steps from restaurants and bars.
Selim was a great host, very helpful and easy to communicate with at any time. If you consider staying in Istanbul, there is no better place. Book one of beautiful Swiss Suites Apartments now ;)
