Very convenient location to the Hagia Sophia Mosque, friendly staff, cheerful and friendly guests, affordable price for accommodation almost on Sultanahmet Square. The conditions correspond to the price - acceptable.
Very nice hostel, great location. The owner is very nice, helps and always tells you. There is no kitchen, but again, you can ask the owner for boiling water and a plate and warm up something, everything is possible. I recommend and will be happy to stay there on my next trip to Istanbul.
