The marmara guesthouse is PERFECT! Everyone was very accommodating and friendly. We used the arranged pick up & drop off to airport which was so easy and helpful. The area is very walkable to blue mosque and restaurants all around. The bathroom is nice and updated. The beds are very cozy. TV in room, free wifi, great view, heater and a/c. The doors have strong locks and there is a safe in the room. They have a printer downstairs too which was convenient for printing boarding pass etc. breakfast was a great variety! We loved marmara for our quick 24 Istanbul layover and definitely want to come back to Istanbul and marmara!
