We stayed three nights in Daniele and Patrizia's place. The apartment is modern, clean, comfortable and very spacious. with all the mod-cons one would expect. It is conveniently located, with only a very short two-minute walk to the U-Bahn Station Märkisches Museum on the U2 line, which runs to most of the main attractions in Berlin Mitte.
Upon arriving in Berlin we communicated with Daniele and Patrizia's colleague, Carmen, who assisted us with the check-in process. She showed us the apartment and explained where things were and how they worked.
Overall, a very enjoyable, affordable and convenient stay! Thank you :)
