Very very small rooms, if you are just going back to your room to sleep then it is fine. We only interacted with 2 different front desk staff and one gentleman was extremely warm and friendly, the other was more lukewarm.
Breakfast buffet for 13€ is very good, there is hot savory options, sandwiches, fruit, pastries , lactose free milk and various juices. Lots of late night food options and grocery stores near by.
