The location really is fantastic if you're in town for a few days and want to hit the main sights. If you're in Berlin longer, you may want to experience one of the districts where people actually live, but for a long weekend this was perfect. This is a serviced apartment, so like many people have said, it's very bare bone, but it has eveything you need. Heinz has fixed most of the things people had complained about, e.g. there are a large(-ish) fridge with freezer and a toaster now, there are curtains on the windows, and even a washing machine. But still no microwave ;-) The apartments are managed by a company that has a lot of apartments in the area, they are pretty responsive, but they can't really help during the weekend. The apartment is also quite large for German standards, except for the bathroom, which really is tiny and has no lock. An issue are the very thin walls, we could hear the kids upstairs from us running around at 6am as if they were in our bedroom... So bring ear plugs.
