Very clean, good space for up to four persons, host was very responsive to questions and a few minor problems with the apartment. Location is great, a few minutes walk from Hagia Sophia and the Sultanahmet mosques, very atmospheric, lots of restaurants and small stores right there. We were initially concerned that the throngs of tourists on the streets might make the apartment noisy, but then we realized that it isn't a problem. Kitchen was somewhat sparely equipped but adequate for four of us. Overall, a smooth and enjoyable experience.
