Leonor's apartment is beautiful and spacious, just as it appears in photos. We had all the amenities that we needed. Having a powder room separate to the bathroom was handy. The bathrooms and kitchen are modern and well-appointed.
The immediate neighbourhood is quiet and peaceful, but very close to a large shopping area. We picked the area as it was close to a conference we were attending. It's not in the city centre, but it's an easy commute on the U- and S-Bahn to get to the centre of Berlin. The closest station is less than 5 mins walk from the apartment.
Communicating with Leonor was easy; she organised a friend to let us into the apartment when we arrived.
We would recommend Leonor's apartment and visit again :)
