Meininger are a reliable, comfortable, affordable chain and Hamburg is no exception. The staff are friendly, helpful, knowledgeable and happy to speak English. The hotel is clean, the rooms sizable, the beds comfortable, and the showers great. It's really close (500 m or so) from Hamburg Altona train station which has local, intercity and ICE trains. The breakfast is worth investing in; although it can get a bit crowded in the breakfast room, there's always enough food to go around. They're more than happy to print off etickets (we found in Germany it best to always have a paper option of anything you book online), book attractions for you...don't have anything bad to say about them.
