There were several nice things -- the location was great; the place was cute and cozy; communication with Kirsten was easy and smooth. There were plenty of drinks and snacks, which we enjoyed very much.
We experienced a couple of problems, though.
Sewer smell: Although there was a diffuser in the bathroom, we could still smell a sewer smell pretty strongly. Probably this was the biggest issue we experienced throughout our stay.
Bed: Another problem is that one of the beds was small (< regular queen-size), and it was very hard for two people to sleep together. One of us ended up sleeping in the living room.
Noise: The windows are not fully sealed by design. On some nights, we could hear noise from neighbors, which woke us up in the middle of the night a few times. We could hear car noises every night.
Light: A minor issue is there wasn't enough sunlight as the place is located in the semi-basement.
