Yearn's communication before our arrival at the apartment was excellent and his instructions for key collection and getting to the apartment were so easy to follow. Even though we did not meet him, he made us feel very welcome. The apartment was very clean for our stay and incredibly well-located. Everything was as-advertised and worked very well. In our opinion the Prenzlauer Berg district of Berlin is by far the best to stay (and we saw a lot of the city during our 5 day stay over New Year). It is trendy without being gentrified and incredibly safe at all times of day and night. The transport links to the centre are fabulous and we even walked to Alexanderplatz on our first day. Eberwalder Str (5 mins walk) is on the U2 line of the metro and Prenzlauer Allee (5 mins walk in the other direction) is on the S-bahn (overground). If you're a keen walker (we did on average 20k/25k steps a day) then you'll enjoy walking most places from the flat anyway! We loved our stay and wouldn't hesitate to come back. PS: I highly recommend Neo 1 Café on Lette Str for breakfast - the staff were lovely and we got to know them very well.
