As stated by the headline, you will travel here to a mini-cozy paradise. The communication with Siu was super fast: we knew that we would be a bit earlier than 15h at our flat and after texting with Siu, we were able to check-in at the time we arrived. The flat itself is an all-you-need package with a bedroom, bathroom and a small kitchen (exactly as described in the advertisement). We travelled to Vienna for sightseeing and experiencing the city, so that we mostly used the flat for sleeping (didn't use the kitchen at all). If you are planning to spend more time in the flat or do mobile work from there, it might be too small.
However, for our purpose it was just perfect. There are quite a few great cafés in the vicinity to have a proper breakfast. Only the connection to the city center was in my opinion good, but not perfect. Almost independent of the destination, we spend around 25-30mins for travelling. Still, that's not a problem. Thanks Siu for the nice stay!
