As mentioned in other reviews, it is very noisy but it was fine for us. We found it easy enough to sleep through.
The space was big enough for 2 people.
Our only negative was there was only one bed. In the pictures there were two beds. We had one bed and one mattress on the floor and a broken bed frame against the wall taking up space. I emailed Yuka to ask about it and she said the previous guest had broken the bed and they didn't have time to fix it prior to us arriving. Hopefully it is fixed for the next guest.
