I recently stayed a the Doubletree following a Rhine River Cruise. I was very pleased to discover the doubletree was a very short walk from the terminal where I left my cruise. No cab service was required. It is also very close walking distance to Central Station for trains. City tram and bus service was also close. I showed up at the hotel around 9:30am and was checked in by 11:30. My room was pre-assigned so I had to wait for cleaning service to get in but they expedited things for me. I had an Executive room so I was given access to the lounge while I waited for my room. The staff was friendly and cheerful! They give you hot cookies at check in. Yummy! The guest service desk staff were excellent! The hotel was extremely busy but they did their best to accommodate everyone. My room was small but what a fabulous view! Sky lounge was great and the best view of the city around! They have Starbucks on the first floor and also rental car service counter. I highly recommend this hotel! Only problem with doing so is there will be less space for me upon return!
