It's an Adagio so it's brilliant, spacious quiet rooms with working kitchens, and I think those fold up beds are brilliant. It feels more like an apartment than a hotel.
The only downside is behind the hotel it isn't a particularly nice area. It's the main tram station, so think Cardiff Central bus station from the 1990s and then some. Most people are fine of course, but expect beggars, gangs of youths, occasional weirdos shouting abuse, rude and even aggressive shop staff.
Really nice hotel in a not great area, Bremen's nice but best not go out late there, and do your shopping in a different part of town.
