4/10
Positive: Quite a good location for going to the Frankfurt fair (Messe) by train.
Negative: Only one person speaking English in the hotel so very difficult to ask for something when he is absent. The room, very expensive for one single bed, is quite large but has major issues like some lights not working, no curtain or pane at the window (nice if you like to wake up very early with the sunlight) or no shower curtain at the bathtub (not very convenient when having a shower). The hotel is globally very noisy so no hope for sleeping after 7 in the morning. The breakfast is not so expensive but it is very limited.
