My window were on the street, and it was noisy, so the only option was to close window tightly, then noise is removed mostly, but lack ventilation. The acceptable solution is to widely open window in advance to get fresh air and close it for the night. That's the only inconvenience I've experienced.
Nice location in 10 minute on foot distance from the main train station, as well as near main street. Walking to the main square takes 10-20 minutes depending on your speed. 1 minute to the main tram line.
Staff is friendly, WiFi is good, early breakfast, at least two common WCs (actual for the rooms without ones).
There are also rooms with shower only for reasonable price.
I liked much all-day (24h) entrance to the hotel with your key, and you can check-out any time of the day!
