Isik was a wonderful host and did a great job of making us feel welcome and accommodating us in any way he could. His downstairs neighbor was just as kind and generously gave us some turkish tea and chated with us on multiple occasions. The apartment is beautiful and comfortable, and the location is prime as it is a 2 minute walk from the metro station (which connects to pretty much anywhere in the city and is an easy system to work) as well as close to Istiklal/Taksim square. I highly recommend that if you're visiting Istanbul you stay here! :)
