We stayed for one night when we landed at Frankfurt.
It was good enough for this short stay: clean, quiet and comfortable room, basic breakfast, nice staff, and its location close to a major station to move on to another city on the next day.
The only drawback was the shower room that was not completely sealed. We couldn’t help splashing water onto the bathroom floor.
Much better more than my expectations. The room is not big as same as others but well design especially USB and HDMI under the TV. Breakfast is also great
Fire alarm just before 7.00am caused by a smoking toaster. No apology given, confusing instructions (one member of staff said to wait until police and fire services arrived, another member of staff said to go back to the room), general chaos. Good job it wasn’t a “proper” fire. Also not clear on booking that the sauna was only available for an extra charge (10 Euros) and prior notice was required.
