What a great experience staying at this apartment. First the caveats: it is a third floor walk-up and it is near a mosque (as in everything in this part of Istanbul) so non-Muslim travelers should be aware that they may be awakened by the predawn call to prayers if they are light sleepers. Neither of these should be a surprise (they certainly weren't for us), but I wanted to mention them in the interest of full disclosure. Next the pluses: They are very good at their communication before and during the visit, even speaking directly with our cab driver from the airport to make sure he knew how to find the apartment. The apartment itself is great. You notice as soon as you enter it how light and spacious it is. A fully equipped kitchen, plenty of space and lots of hot water (a must for a family of four), and a great view. And the location was ideal for being able to walk to all kinds of restaurants, shops, museums, and sights (Hippodrome, Blue Mosque, Hagia Sophia, Topkapi Palace, Grand Bazaar).
