Martin was a great host and both me and my wife really enjoyed our stay at his place. On the first day of our stay he came to meet us, showed us the place, gave us some tips and directions for sightseeing in Vienna and overall was very nice and polite.
The apartment itself was as described, in a very convenient location.
Overall, I am very happy with the choice we made and if visiting Vienna again one day I'd be happy to stay at his place again.
Thanks Martin!
