Mahdis is very very good person, very generous, sociable, and kind. And her sister is also very good. Her house is very nice and cozy and she offered me very tasty Iranian food, the location is perfect to go anywhere in Istanbul. Her house is very close to the Topkapi Ulubatli metro station about 7 minutes walk. I had a great time and I hope to return to Mahdis's house again. Thank you very much to you and your sister.
