David is an outstanding host. I can only recommend his place for any kind of visitors - be it family couple or bunch of friends. You are living 10m away from the main tourist street in the European Istanbul part, but enjoying a quite place like if you're living completely outside of the main city. 2 full bedrooms with a separate bathroom each, great big size showers (tropical shower heads), large kitchen and comfortable living room won't let you walk away with any open wishes.
The flat is full of small, cozy details, which make you feel living in an authentic Turkish place. It's not 'sterile' like 80% of other hosting opportunities.
If you're arriving extra early (like we were) - just talk to David, chances are he will be able to accommodate you apart from main arrival hours.
