we stayed for 4 nights in this very friendly hotel. I had been looking for rooms for three people for a trip to The German grand Prix and all the local hotels in Hockenheim were fully booked and so were many in the surrounding areas. I found this hotel from a trip adviser and google search. Unfortunately there was little online info but I took the plunge. I was in contact with Herr Leidolf by email and he was very helpful. We booked a four bedded room at €100 per night (for the room not per person) with €5 each for breakfast. The staff are all very friendly and the hotel is spotlessly clean. The hotel did not seem very busy when we were there which was a shame as it has owner and staff links with Hockenheim and could so easily have capitalised on these links to promote itself for accommodation for the Grand Prix.
The hotel is in a mainly residential area but there is good rail links 5mins away by foot and a few bars close by; by car it took us 30mins each day to get to the circuit, Hockenheimring without any problem on the Autobahn. Mannheim is a lovely city. I would thoroughly recommend a visit and would recommend The Hotel Hanauer Hof.
