This is a studio apartment, fits up to 3 people.
Location is great, just 2 minute walk to U-bahn and tram stops. Neighborhood is lively, full of shops, bars, restaurants, yet the apartment is on a side street, residential buildings that is as quiet as you can ask for. There are pharmacies, supermarkets within walking distance.
Did not spend much time in the apartment itself, but is simple, well furnished, bathroom was clean, kitchen is fully furnished, and the full service (auto grinder/brewer) coffee machine was much appreciated.
The only thing I can suggest to improve is to perhaps install a handle on the shower wall when you get in the tub. I am used to lower height bathtubs, and as I had a foot injury a couple years back, I find it somewhat harder than necessary to get in and out of the bathtub.
This place will be at the top of the list when I visit Berlin again.
