The apartment is very well-located in the hip area of Prenzlauer-berg. It is a beautiful neighborhood, with great architecture, lots of trees, great restaurants, plenty of places for good coffee and hipster shops. It is also very conveniently located with regards to public transport, this makes it easy to get to the city center and explore the rest of Berlin.
The Apartment itself is also in a beautiful building and has all the amenities needed for a comfortable stay - wifi, kitchen, good second sofa bed etc.
Communication with Michele is also excellent and timely. No delays in responses whatsoever.
There are, however, a lot of plants in the apartment that need some TLC - i.e. they are dying or beyond the point of rescue and may require replacing. Also, keep in mind that when you are in the hallway you need to be very quiet to minimize any noise complaints from the neighbors. This didn't bother us, but if you are traveling with small children or plan on going clubbing at night this might be an issue.
In addition, I always prefer to be welcomed in person upon arrival. This can either be the owner of the apartment, one of their friends, family members or a cleaning lady.. It is just nice to have someone show you around a bit to help you settle. We were asked to pick up the keys across the street (in a tiny tobacco shop) and let ourselves in.
Overall, a nice and comfortable apartment that can be used as a good place to explore the rest of the city from.
