We were welcomed warmly by Martina upon arrival and shown everything in the apartment, as well as the great local spots to eat, drink and shop at. The apartment itself was very spacious, clean and comfortable - was hard to get off that couch!
We tried as many of the recommendations as possible and can confirm the hosts have great taste - Max & Moritz very enjoyable - and, there's a very good supermarket around the corner for those wanting to cook for themselves. I would say the kitchen has all the basics you need, but think it's better and easier to eat out - it's not a chef's kitchen, but we didn't need one.
The location was also fantastic - so close to the metro, shopping, all the bars you could want - very easy to get into Berlin proper.
One tip for a fun way to see Berlin is to do the Fat Tires Segway tour - highly recommend!
A very comfortable stay - only one small thing, the beds each side are not separated by a floor to ceiling wall - only a problem if you really need your privacy from other guests, if not, no big deal.
Loved this place and thanks so much to the great hosts :)
