We're very pleased with our stay at Yusuf&Erol's place. The place was what we exactly expected.. and the hosts went far than our expectations! Everyone was very accommodating and very approachable. We felt secured in the place. There's always a cup of tea/coffee and biscuits/cookies downstairs hehe. The location is very good esp within the old town.. 10-15 mins walk to the main attractions like hagia sofia, topkaki palace, basilica cistern, and on the other side, grand bazaar & spice market..it's very accessible to the tram station, 7mins walk to çemberlitas... and 26mins tram to Taksim square. Overall, we highly recommend it! Very good location and lovely hosts!
