If you are going to Hamburg and want to stay in a modern, luxurious place in the center of the city, consider staying at the Side Hotel, located in the inner Alster lake, designed by architect Matteo Thun. It is one block from the shopping delights of the Gänsemarkt, where you will find boutiques from established clothing and accessories brands as well as up-and-coming young designers. The closest metro stop is Dammtor and the Congress Center is less than a kilometer away.
The hotel has 178 rooms and suites, and a lovely spa that uses products from REN (an upscale UK skincare firm that does not include chemical additives like sulphates in their creams and cleansers). Double rooms start at 160 EUR (if you reserve well in advance via the hotel website, you may get a lower rate).
