The apartment was nice and clean enough, and although I could hear noise from upstairs, it didn’t bother me much. There is a company that serves as the main point of contact, but I was able to get in touch with the owners when there were more urgent issues.
They tried to be as helpful as possible with some pest/rodent control problems I had during my stay, but it seems like these problems are unavoidable to a certain extent in a basement apartment, especially in the summer.
