We go a lot on reviews when selecting accommodation. All reviews were excellent and accurate. The guesthouse is clean, breakfast on the terrace is a banquet! We loved the pancakes included. Marmara Guesthouse has a good location in the old historical area of Istanbul. The streets are cobbled and area quaint. Walking distance of Blue Mosque, Hagia Sophia, Basilica cistern, Topkapi Palace, local bazaar and many restaurants. We can highly recommend Terrace restaurant next door in Hotel Tria. View of the sea, excellent food, service and good prices. Not open Monday's.
