Over the last few years, business has taken me to Heidelberg several times and I've tried a few of the hotels. The Crowne Plaza has become my favorite for several reasons. Nice clean, friendly hotel with a great location. The only thing I didn't 5 star was comfy. However, Its not their fault, just like all Americans in European hotels, we prefer fluffier beds and more TV in English. This hotel has a great breakfast, many restaurants within walking distance and a nice bar for evening relaxing. The club lounge is quiet and convenient. They also have a courtyard to have a coffee and watch people and traffic walk by.
I have to give the staff a huge thank you. On my last visit, I was there for only a couple of days and did not have much luggage. I left behind a favorite shirt. Once I got home, I emailed the hotel who found my shirt and mailed it back to me in the USA. Thank you so much!!!
