We went there with a group of six. We just made the reservation a day before arrival. Everything looked fine and clean. There also is a pool which is for all the owners in the building. But most of the time during our stay we were the only ones making use of it.
Conclusion: we had a great time!.
I would recommend staying here. There is a big supermarket within walking distance and the centrum is on a 15 min walk aswell.
