I stayed at Isik's place together with four friends for a couple of days. It was a perfect base to discover the city because the location is very nice and Isik provided us with a public transport card. From the very first moment, the place really felt like a home to us.
The house has two double beds but the couch is big and comfortable enough for a fifth (or even a sixth) person to sleep on and because the apartment is very roomy you don't get in each others way.
Isik left us a lot of clean towels and an extra blanket and there even was tea in the kitchen.
Isik is a nice host and his apartment is perfect, I really recommend it!
