We stayed in July and August of 2018, and enjoyed our stay. The location is really nice and the U and S-bahn are really close. Especially useful was the fact that the station is a ring line S-bahn station, meaning we could get anywhere in the city in less than 45 minutes at any time.
The neighborhood is very vibrant and fun, and also pretty cheap. The Indian and Vietnamese restaurants very especially fast and nice. There are a few supermarkets next to the U+S station and you can find anything you need there.
The greater area is the most lively and relaxed one in Berlin and the place is ideal for younger people.
The apartment was very pretty and even though it doesn’t face the street it’s still very bright. It is also set up so it is not cluttered but is also very comfortable. There is no TV which we liked and the WiFi is reliable but not too fast. The kitchen was okay.
We loved the tall Altbau ceilings.
The only real issue is that the place was not spotless, but it was not dirty, and that the washing machine was broken.
We would recommend the place to young couples and small groups.
