I stayed at the Grand Elysee Hotel during a business trip to Hamburg recently, my 10 day stay was outstanding in every respect.
The ambience of the hotel is wonderful as are the staff, restaurants and bar, the hotel is not cheap but if you want to indulge yourself this is the place to do it. The art collections on display throughout the hotel are something to behold and a great credit to the owners who have allowed these to be shown in their hotel.
The hotel is located in an area close to gardens, lake, rail station and a pleasant 20 minute walk into Hamburg City centre.
Stay....you won't be sorry.
