Make sure the host reply! In my case they haven’t received the message that we were coming. The room was not clean when we arrived. But it was ok because they walked me into another place so I could shower and go out. When I got back in the night it was clean and ready. The building itself is very noisy, specially around 4am. That makes sleeping quite difficult. I’d buy some earplugs to be able to sleep if I was there for more nights.
