It’s a great location to get around, easy access to Frankfurt Airport and may of Frankfurt’s parks via the metro, there are many places to eat nearby. I stayed on the 9th floor in a single room, it was really clean except for a dusty shelf above the clothes rail, which I only noticed the night before I was checking out. I did find it a little disconcerting that the fire alarm system, only seemed to exist 3/4 of the way down the corridor on the floor I was staying on. I can’t say this for all rooms but my room had a battery operated smoke alarm, the type you would have in your own house. If this is the case for all rooms and if a fire were to happen, it could be sometime for the smoke to reach the fire alarm system in the corridors, delaying of course the rest of the guests staying there from being alerted to evacuate.
