I wouldn't recommend you book this place if you want flexibility in your stay. I requested to shorten my four night stay by 1 night. I was within the timeframe to request this, and the air bnb website said I would get $85 back. My request was rejected, but then I received a message saying the owner had offered $45.
On another note, the place is really small and the front door to the apartment was really basic and felt more like an internal door than an external one. You could hear everything going on in the hallway, and because the place is so small that made it hard to sleep.
