PROS: The location is fantastic, on a tree-lined residential arterial just blocks from Broadway, which is a nice neighborhood commercial district with cool shops, drinking establishments, etc.
Communication was great and hosts will let you check in early if the room is ready. We didn't get to take advantage of that, but it was a nice touch.
The space is pleasant and casual, with good light considering it's in the basement. There is a roomy main room/kitchen, with a very well-stocked pantry (when we were there), at least compared to most AirBNBs I've stayed in.
Maybe not to everyone's taste, but I REALLY liked the firm foam mattress.
CONS: The unit is accessed by somewhat narrow stairs, so may not be a great choice for people with mobility issues.
Ceilings in the basement are lower than what I would consider standard, so if you're much taller than 6-1 or 6-2 that might be an issue for you.
There was a bit more noise from the upstairs unit than I would have liked. They weren't doing anything wild, it's just that sound seems to travel a bit between main floor and basement. Not a trip-ruiner by any means, but enough to warrant 4 stars instead of 5. I've mentioned this to the host so if there's anything they can do for future guests I'm sure they will address it.
All that said, I got a good vibe from the hosts and I think they seem to care that their guests have a good experience and overall we had a good stay.
