Hotel is conveniently located next to the tram line from the railway station and on the border of the old town. From the outside, the impression is a bit confusing because hotel entrance looks a bit cluttered. The room was on a good Crowne Plaza standard.
The service was also good. We also used a swimming pool and sauna. That area looks outdated and a refurbishment would be very much needed. The hotel is not cheap I guess mainly of Heidelberg tourist attraction reputation. I think I would look for the better value of money alternative next time. Maybe I would consider staying in Mannheim which is not so far away and with much lower hotel rates. I stayed here for two nights in May 2015. Booked on ihg own website.
