Alexis' flat is a great place to stay at in Istanbul. I did not meet Alexis in person, but his father showed us the place when we arrived. He was so kind, altough we arrived way too late because our plane was delayed. He did not speak any English, but it was no problem because he has a very good way of communicating amd made sure we saw everything we needed. The area where the flat is situated offers a lot of nice restaurants, especially for breakfast (go to cuma restaurant just some steps away from the flat).
