I had a negative experience here. Would not book it again. I have booked a duplex apartment with a views to city center, but got a downgraded apartment in a inner yard. The worst part was that the receptionist only admited that when confronted about the downgrade. He did not seem to keen to help, just said to contact booking.com if he have any complains.
The room look dated (walls full of fingerprints and small sraches, bathrooms were missing hooks for towels, some spots on the bed covers). The kitchen had all sorts of diffent cups and glasses, something you would expect to see in youth hostels. It does not look like it is on the pictures. I guess they were taken after the renovation and not updated for many years.
One plus for this place is its location. It is 15 - 20 min walk to the old town. There are also many nice bars and cafes around the hotel to choose from.
