We used the room for three of us (my parents and me), and the space was fine. We can actually sleep on the big bed, but there's also a small one that can be used. They provided small treats and other things within the room which is very nice! Location is really close to the bus station so it's very convenient to go to centre. The bathroom was shared with the host but no trouble at all! They were very careful checking after our use to make it more comfortable.
On the other hand, it is on the top floor so again if any next guest have a lot of luggages be mindful of that. And it is quite close to the railway so it can be noisy. I'm ok with it but my parents are older so they were quite sensitive about surrounding noises. Also, in the bathroom, I think it would be nice to prepare some clean towels for guests. We did bring ours but based on my previous Airbnb experiences I think that would be nice!
