Really nice apartment in a fantastic location - we were four guys who were looking for a fun weekend n Friedrichshein, and Markus's apartment was definitely able to provide. Markus was accomodating with our arrival time (delayed flight meant a 1am arrival, though Markus met us for no extra cost), was friendly, and gave us some good tips for places to go in the local area.
The location is perfect - very close to the restaurant area of Fhein, ten minutes' walk from the numerous bars and clubs nearby, as well as metro stations. The apartment itself was fantastic - great decor, lovely kitchen and fantastic balcony which we could chill out on before going out. Great sound system too.
The only issue we had was with the beds - when we booked the apartment there were two bedrooms in the pictures, so we thought we'd have two people to a room. When we arrived though one of the bedrooms were locked and all four beds were in one room - a bit tight for four guys, partiularly given that some of us would stay out later than others. Thankfully this didn't spoil our trip, and I would definitely visit again with a smaller party.
Thanks for hosting us Markus!
