We stayed at Mandy's apartment for five days and it was absolutely great! She was easy to communicate with, and when we arrived she tried to make us feel right at home by showing the whole apartment and giving us tips for our stay. The apartment itself is very spacious, clean and - most importantly - in a great neighborhood of Berlin. Friedrichshain is a lot of fun! If you wanted to go some place else, that wasn't a problem either: the apartment is very close (5 minute walk) to big S-Bahn and U-Bahn stations. I would definitely recommend this place for everyone who would like to experience Berlin!
