We ended up checking out at 330am due to:
1) The air conditioner dripping condensation all over the headboard and pillows.
2) The floodlight outside the window shining directly into the room. We tried to hang the blanket over it to no avail.
3) The neighbor upstairs stomping around from midnight to 3am.
I've never had such a terrible experience. The placement of the air conditioner and the presence of the floodlight indicate that this AirB&B is not well thought out.
