the photos are more like glamour shots of the room, the actual place is much smaller than it seemed in pictures, not nearly as bright. the host told me it's 35 to 40 sqm when the entire place is ~25 sqm at best. To call it a studio, it means all standard hotel rooms can be called a studio. The reason I book on airbnb is to have a nice spacious unit, which this place at 25sqm (~269 sqft) is not. The price I was paying (us$97/night including all fees for Istanbul in Dec is on the high end) along with the claimed room size plus the good reviews made me believe it must be a nice big place, and I was solely disappointed.
The only saving grace was that Agia was apologetic for exaggerating the room size unintentionally and was cooperative to allow me shorten my stay to 1 night, with cleaning fee my 1 night cost me $109, but I didn't hesitate to move out. The building and surroundings are not flattering either. If you are a light sleeper, be aware of some honking and human noise at night.
