I warmly recommend Giamp!
When I arrived in the evening, I directly got invited to share pasta and a beer with flat mates and friends.
The atmosphere was so relaxed and friendly so I felt comfortable like at home.
The room was clean as well, wifi is working well and it's only walking distance from the city centre (15 minutes), also there are many bus connections directly in front of the house (to the city centre, main train station,...)
Thank you, I appreciate the warm welcoming atmosphere here so much :)
