Overall 'meh'. This hotel is ok, but we wouldn't recommend it. The room was clean, though not cozy or atmospheric.
It's a 15 min walk from the Eifel tower but close to the metro and it's on a very busy street.
The service wasn't exactly great. I asked beforehand for gluten- and lactose free options for breakfast. At first, they simply said there weren't any. I complained and they promised me there would be gluten free bread (I would have been fine with just some bread and jam), but when I asked for it on the morning itself, it wasn't there... I just left it at that and got breakfast myself.
