Evrim's place is situated at a perfect location, at the same time it is very quiet and calm! I recommend taking the metro when you are going up the hill since it could be quite tiring :')
At the same time, the place is about 5-10 min walk from Sisana, a central metro station. And right next to great breakfast cafe, you might even be tempted to have all of your breakfasts there!
The house is nicely decorated and give you quite an exquisite feeling the moment you walk in. Evrim and Mustafa were very nice and quite hospitable, they provided us with all the information we required.
Would be looking forward to my next trip, Evrim's place will be the spot I look for in Istanbul.
