I stayed at the radisson sas in frankfurt, it was a special occassion, my parents wedding aniversary. i contacted the hotel with some requests and they delivered on all. very friendly and efficient staff, it seemed to me the staff were invisable but when needed were there to help. very relaxing and homely. a deserving 5 star category. ultra modern decor. rooms were a little on the small side but very well appointed. the location of the hotel was good, central but still a short taxi ride to the main shopping and eating areas, maybe eur 6.00 taxi fare. the breakfast room is on the ground floor, again very modern and spacious. excellant choice for breakfast, full hot buffet, all types of juices, breads and cold meats. the only negative is the cost to park the car, eur 25.00 per day. i though the hotel would give some kind of concession as they own the car park. overall, an excellant hotel and will definitely go back, well done.
