A hidden gem
In the shadow of the Blue Mosque, just blocks from Hagia Sophia and Topkapi is a small elegant hotel, with about thirty rooms, a terrace overlooking the Sea of Marmara and a good restaurant. The service is very personable.
Each room has a little mini-Turkish bath, a shower with a big urn to fill with water and scrub yourself. Breakfast is included, and they have a very nice buffet. Taxis, ferry schedules, and other tourist information are readily available.
