I stayed at the hostel for 1 1/2 weeks and I can only recommend it. The staff was very helpful when I needed to stay another night and check in and check out were super easy.
The rooms and bathrooms are clean and there are enough on each floor that I never had to wait. Yes, you can sometimes hear your neighbors through the wall, but while I was there everyone respected the 22:00 noise curfew. And even though my room faced the street it wasn't as loud as I expected. The location is great and you find everything you need in walking distance.
