An acceptable space, a few things to keep in mind:
1) Room was dusty: there was visible dust on closet walls (the kind that takes a while accumulate) as well as on the two bookshelves in the room.
2) Room has no less than 4 doors (6 if you include the French doors blocked by one of the beds). 1 door to enter the room, 1 that leads to the bathroom, and 2 doors for 2 separate closets.
3) Room sleeps 3 because there is a twin bed and a full bed.
4) Located near the SD airport, you can hear the planes overhead.
Due to lack of timely communication, a result of the nature of our visit (business) and timing of our arrival (very late at night), we weren't able to communicate concern 1 (see above) until after we decided not to stay the second night of our two night stay. Betsy indicated she would have been more than happy to vacuum the room and dust the bookshelf had we communicated in real time.
While Betsy was certainly responsive, I think dusting and vacuuming would be a part of the standard preparation of the room for guests.
