We really enjoyed staying in Hikmet's flat. With two bedrooms it was plenty big for just two of us, and would be perfectly suitable for four adults. It's a basement flat so there's not much natural light, but you can't beat the location - a three minute walk to the Hippodrome, a five minute walk to the main street, and less than ten minutes to the Blue Mosque, Hagia Sophia, Topkapi Palace, and more. Each day someone came and gave the flat a quick tidy, and Hikmet provided a Turkish breakfast on the rooftop one morning. Overall he was very helpful, and the flat was perfect for us during our week's visit.
