I stay here for work purposes, the hotel does look slightly tired, but this is not something to be put off by. All the hotel staff are very polite, friendly and very happy to help. Check in/out is a smooth process that doesn’t take long. The rooms are good, clean, have all that you need (even 1 English plug), tea coffee facilities, toiletries etc. Also a chocolate is left on your bedside table each day, along with some herbal sprays to help you have a good night sleep! The air-conditioning is ok, I wouldn’t say it’s the best as I have it on 10 during the night and I am not cold, usually this would be freezing, but it does cool the room. There is wifi throughout the hotel, I think normally there would be a small charge, I get this included with my company. If you join the rewards scheme you are given a voucher for a free drink in the bar. I had breakfast each morning, excellent selection of food/drinks, also have paper cups to take your drink away with you which is great in the mornings. I have note eaten any evening meals in the hotel so unable to comment on this. I haven’t used the pool yet, colleagues advise me that is it ok. I use the gym which is small, but has all that you would need.
The hotel is very central for Heidelberg, you are within walking distance of pretty much anything. This is a great place to base yourself for a visit to Heidelberg!
