I stayed at Deniz's place for four months during a semester long university exchange, with one other roommate. The place is so cozy and within a great location of the city. It is in a cute neighborhood with lot's of nearby coffee shops and restaurants. It is super easy to the the Osmanbey metro station (less than 10 minutes walking), but it is also quick to walk all the way to to Taksim and even Besiktas. Deniz was extremely easy to communicate with. She helped us a lot ordering water, paying utilities, helping with troubles with appliances and anything else we needed. I felt so at home here and if I am ever lucky enough to be back in Istanbul I hope to stay at Deniz's place again :)
