Our stay at Marina's and Sascha's apartment was thoroughly enjoyable. The apartment was super clean and the furniture was very comfortable to sit and sleep at. There are supermarkets right around a corner, so that you can get any food you wish. Public transport is perfectly accessible. The sbahn takes you to the Danube in 15 minutes and the subway to the city centre in 15 minutes and neither station is further away than a five minute walk.
Marina and Sascha checked in with us every other day to see if we needed something. The internet wasn't working one morning and they took care of it right away.
Recommendation: There is a really nice cafe down the street (chrivo) serving delicious breakfast, self made cakes and coffee and the owner is such a nice person.
