Emil and Faigy's apartment is a comfortable, compact place, with everything needed for a short stay. It was 5 minute's walk from Friedensbrucke Ubahn station, so very accessible for the centre of Vienna. There are good shops, cafes, bars and restaurants close by. Hopefully the issues with hot water will get sorted soon.
We did not unfortunately meet Emil and Faigy, and had intermittent communication with them. Overall, we were very happy at the apartment, which we found cosy and peaceful .
