Deniz's place was perfect. It's comfortable, quiet, and very well-equipped. Located at a dead end, so no car noise, and at the same time within walking distance to lots of great cafes and restaurants.
For some reason, it was hard to order Uber or BiTaxi directly to the place so we were walking down to Tophane Parki (it's 4 min walk) and took a taxi from there. Anyway, it was very convenient.
Thank you so much, Deniz and Murat for this beautiful place and for taking care of us!
