I stayed at the Ringhotel Tallyman on a recent business trip to the Hannover exhibition. Overall I would highly recommend this hotel. The staff members were very courteous, even going so far as waiting up for me until after 3:00 AM when my plane was delayed. The food is something that is highly touted at the hotel, and it isn't oversold. It was by far the best meal I had while on this particular trip. My only complaints were that the wireless internet did not work in my room and it was a little bit of an inconvenience to work from the lobby. Most rooms did have wireless though, I just was one of the unlucky ones. Overall I would strongly recommend this hotel, the value was great, access to the Hannover fairgrounds was quite quick (straight down a major highways), and Bad Nenndorf, while nothing spectacular, is a very cute and warm city.
