Apricot Hotel, Istanbul Sultanahmet
We stayed there Oct.-Nov, 2013 for 6 nights, both before and after a cruise. This is a moderate price small hotel in an old Ottoman building in the historic section. It is a good value. Very close to the Blue Mosque in the historic section, this was very clean, plenty of hot water, a very comfortable mattress, and had a nice breakfast that included either boiled or cooked eggs daily. They also have a very helpful staff that were great with advice on directions, restaurants, etc. There's no elevator, but the helpful staff was quick to carry luggage up and down the stairs for us.
We arranged ahead for our taxi service through the hotel, and emails we sent were always answered quickly.
