We really enjoyed our stay at Jan's apartment. The apartment was really trendy - my boyfriend particularly liked the interior design. It was quite masculine, a bit rough around the edges, very cool. Jan met us at the apartment when we arrived and provided some great recommendations. Communication was good. We definitely needed longer to really absorb Vienna so we will be back. The apartment itself was walking distance into the centre of Vienna, but there was also a tram system. Only very, very minor things were some noise late at night from the flat upstairs and the positioning of the boiler made the shower over the bath a bit cramped, but neither point would put us off staying again. We had a great time!
