We stayed in Diana's apartment for three nights in the beginning of January. The place really looks like it was presented by photos. Even better. Although we didn't meet Diana- the keys were left for us in the outside locket. So both checking in as well as checking out went smoothly.
The whole apartment was impeccable clean. The beds were made, even spare beddings were left. The central heating worked perfectly. The kitchen is nicely equipped with everything you need even if you decide to cook your own meals. I enjoyed my morning freshly made coffee from the espresso machine before starting exploring the city.
There is only certain kind of unpleasant smell all around the flat. It has nothing to do with cleanliness of it but probably with the sewage system of the whole building.
Connection with the city is so simple. You can easily walk either to Mariahilferstrasse for shopping or to House of Parliament or the very heart of the city. Or take tram, bus or metro not far from the apartment.
One of the best apartments we rented so far.
