Libors flat is located perfectly for exploring Berlin: Right next to a historic memorial in Treptower park (1 of 3 soviet constructed memorials after WW2) and interesting abandoned amusement park (Spreepark), a 5 minute walk from grocery stores (Lidl and Rewa) with all the amenities to make use of them, and a 10 minute walk from an S-bahn station which made getting to all parts of Berlin incredibly easy.
Check in and Check out was exceptionally easy and though we did not meet Libor, as he was working out of the country, he sent great information beforehand and was very responsive over whats app.
