The description of the room/flat was accurate and in a matter of fact we were pleasantly surprised that the flat was actually better than expected. It has all the facilities needed and is quite good looking and modern.
The host was very good and provided all the information we needed for the stay in Vienna. Late check in was very easy and all in all we had great experience with Rene.
The only drawback is that it doesn't take 14 min on foot to the center (e.g. St. Stephen's cathedral), but rather with the public transport or a car. It took much more to walk, but if the weather is nice it is not bad at all.
