3 girlfriends and I visited Berlin to see Christmas Markets, visit some museums, and do a bit of clubbing. We loved staying at Robin's place, as it is very central, incredibly clean, with lovely design elements and totally equipped. When we checked in, Robin spent time to give us really good tips on where to go, what to see, and opening times. He is totally accessible as he lives in the building, and ensured that we were very well looked-after. Would definitely recommend his flat for a weekend in Berlin!
