Marmara Guesthouse is situated in a great location with many great restaurants nearby and short walks to the major attractions of this historic city. While the rooms are not large, they are sufficient, and the bed was very comfortable. The breakfast on the roof was tasty and convenient. We decided to book an extra night, and the office was very accommodating. I will never forget the hospitality and stunning architecture we experienced in Istanbul. I wouldn't hesitate to stay here again.
