Unfortunately a design of the standard room made me nervous to make a shower & toilet because the door could not be closed completely. I was not alone...
This hotel should check each door for the bath even if the standard room is cheap fare ;-( the reception staff were very friendly.

Stayed here during the Christmas market period, so the hotel was very busy. The rooms were clean and warm. Check in and out was quick. Nice location, handy for shops, bars etc. Rooms were modern but the rest of the hotel seemed stuck in the eighties but I liked it.

Radisson has really become an excellent chain. The rooms here are modern and very comfortable. Open bath concept. Very comfy beds and shutter blackouts. You can walk to the historic area. Erfurt is quite charming but hasn't got that much to see besides the 2 churches on the hill, the flower square and the covered bridge - no must see sights.

Positive:
The price is OK. Good views from the higher floors.
Negative:
The smallest and most depressingly furnished 4 star hotel room I've ever stayed in, and nothing like any other Radisson I've ever seen (not in a good way).
