What a fantastic place to stay in Istanbul! Not only is the location ideal in the heart of the old city, which is great for visiting the key sites in the city, but the accommodation itself is exceptional. The room was comfortable and clean, and the staff I dealt with were professional and helpful. I do also have to give special mention to the breakfast offering at the guesthouse; although I don't generally expect food provided at Airbnb, the breakfast selection here was exceptional - what you see in the picture really is what you get! I cannot recommend the Marmara guesthouse highly enough, such good value for money without a doubt.
