I had a 3 night stay in this hotel during Christmas, which it has a buy-2-get-1-free promotion. At 50 euros a night, I don't expect something spectacular but it was quite wonderful anyway. It's a block from the famous Kadewe shopping center with loads of cafes along its street. It's 1/2 block away from the closest metro station Augsburger Strasse. Note that such station does not have escalator / elevators (as many metro stations don't). From airport you may take a bus to zoologischer garten station, where you can take a metro change to there (which requires line change for that 2 stations distance and ups/downs of stairs during the change) or walk from there to hotel that needs about 10-15min.

I guess they upgraded our room so it was quite big with a balcony (kinda useless in winter) where we can see the quiet street and its neighbourhood. The rooms + beds are basic (the professional photos would've fooled you) but clean and comfy. Hotel staffs are friendly and helpful responding inquiries in perfect English. There's also a gym + spa + sauna facility upstairs at 6th floor.

One small complaint would be the free WIFI. Though free, it needs a unique user/password pair per day per device - kind of annoying, and the service gets cut off easily when I reached my room. Overall this hotel is still a great place for tourist to stay.

Vi var 3 damer fra Norge som tok oss en tur til Berlin i oktober 2011. Vi bodde på Alsterhof hotel og var veldig fornøyd med det. Komfortable rom og sentral beliggenhet. Flere gode restauranter i nærheten, bl.a. Hasir restaurant (tyrkisk) på hjørnet ved U-Bahnst.

We spent two nights in this hotel because we had a smart box as a christmas gift. The hotel is really comfortable and clean, just 15 minutes from Tegel airport by taxi, and about 30 minutes with public transportation. If you travel for tourism, the position isn't the best, to get to the centre you have to take two different subway lines, and takes about 20 minutes, but you can easily take a tourist ticket, that also includes the entrances to a few museums, with wich you can also reach Potsdam.
The hotel offers a nice breakfast, with a good choice of fresh fruit, yogurt and croissants.
If you have to choose a place for dinner, the turkish resturant nex to the hotel is excellent!

Great hotel! Extremely clean and well-furnished. We felt very safe while here, and the room was very quiet with a nice view of the courtyard and a view of the street between neighboring buildings. The rooms were a little small compared to what I'm used to in the U.S., but certainly adequate and the quality of our stay was enough to make all the difference!

The beds and pillows were very comfortable, and the linens delightfully fresh! My only complaint was that the duvet thing provided was WAY too hot! The room is kept warm enough you could sleep with just a sheet though. There are no in-room temperature controls, but even as picky as I am I had no issue. It was incredibly cold outside and the entire hotel was perfectly warm without being suffocating. The bathroom, always a telling point of any hotel room, was very nice! Everything was impeccably clean, but remember to leave the door cracked when taking a hot shower as there is no vent fan.

I was unfortunately very ill on our trip to Berlin, and the hotel staff at the desk showed great concern for me once it was mentioned by our guide. There were members of our group who had last-minute changes in their room preferences and the staff were very quick and friendly about accommodating them. There seemed to be a lot of rooms available, even though there were people seemingly everywhere. It was a busy, but polite and inviting place.

The restaurant downstairs was very nice. We visited for dinner one night and had great food at the usual price for dinner anywhere out in Germany. The restaurant staff was perfect. The breakfast included in our tour looked like it was good, but unfortunately I am not a morning person and was unable to enjoy any since I always feel worse in the mornings when sick. As with most hotels, the snacks and fizzy beverages in the fridge will cost you if you partake. Bring your own snacks/drinks and save the money!

I feel like I found a bit of home at the Alsterhof and I plan to return whenever I visit Berlin again.
