The Good:
The host was very welcoming and surprised us by saying "Help yourself to anything in kitchen". The room and bathroom were off by themselves and afforded some privacy. It was easy to find and an easy drive to anywhere in Asheville. The home was away from the road (ie - no road noise). He had fast wifi and even tried to help me print something even though the printer didn't work right in the end.
The Bad:
The listing offered a bed and futon mattress. When I asked about the futon he said he needed to go find one. After a couple of days I decided to just share the bed with my friend. It was not a comfy bed by any means and the futon in the living room was being taken up by a friend of the host.
The room was a bit beyond "rustic" and really needed to be updated. The carpet especially was stained and looked like something that was in my first dorm at college. I left my socks and shoes on for the entirety of the stay. There was always hot water, but the water pressure was unpredictable. There was no hot water in the sink.
The room was advertised as non-smoking, but the host and his friend (who was sleeping on the futon every day we were there...) were smoking "something" and it filled the house with the skunky smell. It was disconcerting to wake up in the middle of the night and smell this stuff while hearing them jam out in the next room on guitars at 3am. The room was tidy, but the rest of the house, less so.
This place is not good for professional types. I'd say it's perfect for foreign travelers and college students on a budget who like to stay up late, among other things.
