Stayed here for 3 nights while attending an EMBL conference. Booking via email was efficient & although we arrived at lunch time our rooms were ready. Decoration was basic but the room was clean and the bed comfy. The pillows were weird - very small! Breakfast each morning was good - hot & cold food available. Boxberg is a bit of a way away from Heidelberg centre so I wouldn't stay here if you want to see the city but it's walking distance to EMBL so good for conferences.
