The busy road did not wake me at all. It really isn’t an issue. We all slept very well.
There ended up being four of us (group started as two and grew to four before we got there), and the air mattress did deflate. This has happened to ours before, as these air mattresses generally don’t last long (and they did advertise that it would be an air mattress); however, we just used the sheets to make up the sofa, and it really was not a problem for us at all, but just be mindful of that if you are booking for four.
As advertised the sink in the bathroom is tiny (not really big enough to wash dishes), and we did use the dishes in the little kitchen area. I happened to have disinfecting wipes, so we just wiped down the dishes with those, rinsed in the tiny sink after and dried with the plentiful supply of kitchen towels. I believe this is a COVID situation, as I see that the kitchen is normally available for dish washing. Either way, we were able to work around the issue, but it is good to be aware.
It is a very cozy, spacious and warm space in a great location. I highly recommend.
