Martin was an exceptional host! He warmly welcomed us into his home and made sure we were taken care of. His apartment is awesome, it's in a location that is off the beaten path and the neighborhood is quite lovely. Definitely check out the Augarten, but make sure you leave before it gets dark (they lock the gates up at night and it's a walled garden). There are a few grocery stores nearby (Lidl, Spar) and Martin has pretty much everything you need to make a delicious meal. Plenty of fridge space for storage. The apartment is also located very close to the Donau Canal and if you ever get too hot you can just walk down to the canal and enjoy a cool breeze or even dunk your toes in for a refreshing break. We highly recommend Martin as a host! He's a really great guy!
