Silvia was a wonderful host, very friendly and very attentive with her guests. The check in and check out were extremely smooth and also Silvia was there to answer any questions or to help out with anything I needed. it was really a pleasure to meet her.
The apartment in which I stayed was absolutely amazing and it really had them all: it was spacious, modern, extremely clean, it had absolutely all the utilities you can possibly think of, very quiet and last but not least very close to a metro station (maybe a 5 min walk to Burgasse Stadthalle U-bahn station).
It will be my pleasure to contact Silvia again and to stay in one of those wonderful apartments.
Strongly recommended to all those willing to have a pleasurable and comfortable staying when travelling to Vienna.
