Didn't see any other reviews on this property, so thought I'd post one...

Stayed several times at the Marriott Hamburg, which is in the midst of the city center and has a fantastic location. Easy to walk from the hotel to most sites in the center of the city, or a short cab ride away.

Train station is even walkable if you don't have bags to carry (and if the weather is nice) -- about 10 blocks away.

The rooms are clean and comfortable, service is top-notch, and the hotel overall I'd highly recommend.

The lounge on the 5th floor is well-stocked and open late. Didn't see a lot of activity there in my stays, but perhaps it was the hours that I visited.

Competes for me (in terms of quality) with Le Meridian in Hamburg, but beyond the view of the lake (which Le Meridian has) the Marriott has a better location.
