Mixed impressions, but not bad overall for a short stay.
Room 5/5: simple and clean, had everything I needed; I enjoyed the bed a lot, it was very hard, but not rock hard.
Bathroom 3/5: shower cabin old and not perfectly clean, but satisfactory.
Breakfast 3/5: I was not as impressed as other people in the comments - narrow selection which is the same each day, instant coffee, but bread and warm soup were ok.
Location 4/5: right by the tram station, so getting anywhere is fast and easy; I was concerned about the noise from tram and asked for the room with windows on the opposite side - slept the whole night with open window with no noise problems at all. We did a lot of walking too, the Old Town is about 40 minutes away (my pace). The district itself seemed very unattractive at first (it's considered suburbs, so no surprise there), but was quite calm during the night (the weekend as well), and after a few walks I found several good local restaurants/bars with very low prices, amazing beer and good food, which you will almost never find in tourist districts.
