As for the loft, we only spent a night here and we did not realize it is on a ground floor with an entrance directly from the narrow street with a tram line. Seems that the space was originally planned for a gallery or a shop and then re-designed into 3 lofts for letting. It did feel like we were sleeping in the street, maybe because it was a Saturday night and the area was packed with people. With windows open we could hear every person passing by, the tram runs almost entire night and it does feel like it runs thru the space (the line is literally 5 meters from the door). Bring your earplugs - that might help. The space is decorated with taste, there were some snacks for breakfast which was a nice touch. The bathroom downstares is very spaceous. The feeling of the loft is something we were picky about, hence the rating, for others it might not be even an issue.
