I’ve lived other ground floor/basement Airbnb suites, and comparatively this suite is very noisy: you can hear people above talking and walking with floor squeaking in high volume. My sleep is light so I could not sleep until after midnight on Thanksgiving night after everyone stopped walking (certainly it’s reasonable that people sleep late on holidays.)
There’s no heater or temp control but it is not a problem for me to handle early winter with the bedding and extra blanket.
Overall the host is nice and the place is clean. If you sleep tight easily, this place is good.
