Marmara guest house is fantastic. And the hosts are also fantastic. The location is super perfect and it is actually on a very quiet and mellow street which is hard to come by in Istanbul. The neighborhood that it is in is also mellow in comparison to just about anywhere else in that part of town. Great rooftop patio as well. So if you don’t feel like being out you can stay at home with a large spacious patio and a spectacular 180° panoramic view of the Bosphorous. Next time I am in Istanbul I will definitely stay there. I also plan to recommend this hotel to all of my friends.
