The hosts were very friendly, gave us a warm welcome and listened to our issues with the hard beds. The mattress contained a board on top, what made it too hard. The hosts organized a cover to make it softer.
There were two other parties (6 guest in total) in the house what caused the single bathroom to be occupied a lot. And other guests took showers including blow-drying hairs after 11.30pm. We complained next day and the hosts reminded all guests to adhere to the quiet times specified in the listing.
In summary, the hosts were friendly but it was too loud, the beds hard and there were too many people using the same bathroom.
