William, the host, was nice. He clearly explained how to get to the apartment and he provided me and my sister with what we needed (towels, blankets, coffee in the morning....).
The aprtment is located 2 minutes from the train station and it takes less than 15 minutes to reach the city center.
My experience was overall good. The only negative aspect I could see is that the room is a bit small for two people. The second bed is an extendable couch which, once opened, takes most of the room. If you are ok with it, then the room is fine for more than one person.
