It was a exceptional experience staying at Muge's house and in Istanbul. We came from the Sabiha airport late evening around 10 PM. But she arranged for our pickup straight for her house and she was waiting to welcome us. Muge and her friends are very warm and friendly. The whole apartment is at your disposal, which was extremely convenient for us. Very spacious and nice home, it as everything which is required (to be frank we didn't even use 1% of what cold have ben used for the stay:)). This place gives a feeling of living at atrue Turkish place in a true Turkish locality. Istiklal street, Taksim square, Galata tower are very nearby, walking distance. Even the old town could be done walking, which we did as a very good experience.
Overall an extremely homely, warm, satisfying experience staying at this place and being in Turkey.
All the best.
