We stayed for a week. Perfect "home" for our first visit to Berlin. It's just a short walk (about 15min) to Hackesmkt and Norbanhof. Both are useful for picking up the U-Banh or S-Bahn to get around the city. And just a short walk (10min) too is the main drag leading up to Prater, the old beer garden, and lots of restaurants. So we were never shot of options for dining. The unit is comfortable, and we selected it for having a washer AND dryer, which meant we could pack less clothing for our trip. Internet wifi was not consistent -- my main complaint, but other than that we loved the unit and its location. (The other is a bit of noise and tobacco smoke from the restaurant and bars across on Friday and Saturday night. It's a third floor unit, but close the windows/doors and it's tolerable.) Definitely will use it again if we will be in Berlin, and recommend it to family and friends.
