WiFi in the room (3rd floor) was not really working, but it was really good on the main area around the reception where there are plenty of tables. U can't stay really late there though. Breakfast is great, but it's only available after around 7:30, so if you need to catch an early morning train u might have some trouble.
If it was closer to the heart of the city and the central train station it would be much better, but it's just ~20" walking, so it's ok.
Funny building to live at, helpful staff, easy lockers, rent a bike option (~10E/day or sth), nice rooms with sheets etc. They offer a great, fully satisfying breakfast as well and it's right next to a train station (not central).
