The place was over all was great. The rooms and toilet facilities as well.
Ist is just a 15 - 20 min Walk from the Central station and only 30 min by foot to the old city center.
The only thing that bugged us a little bit was that the reception only opened at 9 in the morning. So if you want to get an early start in the city bus still need to check out or something else you have to wait until 9 to do so.
But everything else was great and I would recommend the place.
