I stayed at Gasteresidenz for two weeks while working in Hannover. And to say it upfront, I enjoyed my stay very much. Gasteresidenz is not really a hotel but more like a boarding house, geared towards guest who stay for longer periods of time. I had a room on the 4th floor: Large layout, plenty of closet-space, an office area with a desk, plasma tv, the bathroom was rather small, though. Each room has a kitchenette, pots and utensils can be borrowed from the front desk. However, the kitchenettes are rather poorly equipped. There is a sink, a fridge/freezer, two hotplates and cabinets. There is no microwave, no toaster and no coffeemaker. Coffee to go is available in the lobby for a Euro per cup. The breakfast-buffet in the morning costs 9 Euros. There is an inhouse laundromat...one load of washing and drying including detergent costs 7 Euros.
Gasteresidenz is located fairly close to the city center. The tram stop is 250m walking-distance and then its just 4 more stops to the main train station and city center. A supermarket is just accross the street from the tram. There are also bakeries and restaurants very close to Gasteresidenz. They offer on-site parking for 5 Euros per day, but in my experience there is plenty of free parking in the surrounding streets.
Gasteresidenz being not a hotel but a boarding house, towels are only changed twice a week and sheets only once a week. There is no room service, but menus from various delivery services are in every room. Wireless Internet is available, but it gets horribly slow in the evening hours. But I was told, they are working on it.
And if you think, this is just a so-so review...consider this: I got an incredible rate at Gasteresidenz, that made up for all the minor inconveniences. Less than 50 Euros per day, which was just awesome. However, if you are coming to Hannover for the annual Cebit trade-fair, expect to pay a lot more.
So if you are looking for a comfortable, efficient and reasonably priced place to stay in Hannover, Gasteresidenz is the place for you. Staff are very friendly and helpful. But If you want the full business-hotel experience, make reservations at the Sheraton down the street. Next time I'm in Hannover, I will definitely stay at Gasteresidenz.
