Summary: nice host, the accommodations not as much.
The reason for my rating being low is because a person is rating the place where they stay, not the niceness of the host. Here are the issues: this is NOT a fully private Air bnb, as it is advertised. It is also not as "bright and cozy" as advertised. To give more detail, guests are not sharing the basement with anyone else, not sharing a kitchen or bathroom, HOWEVER one has to walk through the entirety of the host's home to even get to the basement. It also does not lock, and the basement shares common areas that the host goes into quite regularly. There is NO door on the bedroom!, the bathroom door is not secure and also can't lock. NO privacy, which can be a very uncomfortable thing for a solo traveller. At any given time the host (or their own company) can go into your space. Not having a door on the bedroom is extremely disconcerting. Also, the fireplace is the only source of heat in the basement. Depending on what time of year a guest is staying, you may want to take that into consideration if you are sensitive to cold. The bathroom is TINY, which would be okay if the photos shown were more accurate and didn't try to hide this fact from prospective guests. One cannot even bend over the bathroom sink to brush their teeth without hitting their head and making a huge mess. There were a lot of dust bunnies and hidden dirt around (didn't appear to be dirty from other guests), likely just from not being occupied for a while. Still, the place should be thoroughly cleaned before every guest. Also-if you have an issue with bugs and spiders this is not the place for you, as there are a lot. I am familiar with basements so I sort of expected it, although it was not nice to have crawly company every couple days.
All in all, this may be a good place for you for a very short term stay, or if you don't mind not having privacy. The host is a nice person and it is too bad it is not advertised a little more accurately, because I would have liked to give a better rating.
