Great place to stay for a few days when you need a place to sleep but dont spend free time in the ro

Liked:while the room was rather small it was very well equipment in terms of electricity plugs and the bathroom, with a lavabo inside the room. it is ideal for a family where not much privacy is needed. It was great that we could put the surfboard bag into a separate storage room on the ground floor.

Disliked:Overall, all went well.
