A pleasant stay in this calm, well furnished and neat, if somewhat austere, flat. Situated on a peaceful street, it gives one easy and rapid access to the centre. And the neighbourhood itself is charming and has lots of amenities.
Our late arrival did not enable us to meet Stefan, only his father who picked us up from the airport (a handy solution). Despite being easy to contact by phone and text, we had hoped Stefan would stop by in person to check on our settling in and go over details such as the heating, the television, the washing machine, etc. (On this score, a little instruction pack for the flat would be useful.) We did eventually happen to meet him by chance on the stairs and hence got to know him superficially.
A minor incident regarding a repair problem on plumbing in the toilet led to an appointment due at 8 one morning. This was unfortunate and should have been avoided at such an early hour.
To sum up, the flat is to be recommended on a good few aspects: location, access, size, fittings, furnishings, cleanliness. However, even though this is an "Entire place" rental, one nonetheless would like a moment's welcome from one's host - even briefly - and in passing gain a few tips on one's stay in Vienna. An Airbnb solution, we thought, is about avoiding the anonymity of an hotel. This flat rather sadly came across as just that.
