We did not have the chance to meet Güner in person but his family was very nice, welcoming and helpful. We had a great time in Istanbul thanks to this apartment that is really well situated and more "local life" than Sultanhamet. The apartment is fully furbished and clean. We never had to take the bus or taxi and only walked to see everything during our 3 days stay. We would highly recommend you to stay there! Thank you again!
