Very nice setup with an affordable price.
Public transport is within an ideal range.
It’s basically like a condo, so you can get good privacy.
I don’t know if anyone would mind it being the basement, but I wouldn’t. It would not remind you as a basement or there than the pipes and windows. You still get some windows and after all. In fact the window setup is better than most motels. Plus, you might be exploring out there during the day, so basement or not it wouldn’t even matter.
The hosts are very nice and approachable! They even helped me parking my car in the driveway. Do make sure you are not showing up with a pickup truck, because that really might not fit in the driveway.
