We stayed in this apartment for six nights in mid September. We were really happy about it. The apartment is really close to downtown (5-10 mins walk) and the area is quiet with no crowds and supermarkets and transportation are around the corner. It is a big and comfortable apartment and it feels very homey. The bed in the master bedrom is big and the living rom is realy big as is the bathroom. Some may be surprised that there are some of Chris' belongings like books in it but we rather liked it, in fact, we took advantage of his guide to Vienna to prepare some of our visits :-)
Chris was very welcoming and helpful. We had requested a cot for our baby and it has been the first time we have been provided with a real one instead of the classical travel cot with no mattress and just the lousy base. This was a real plus and our daughter did enjoy her cot.
The apartment also has a nice little terrace where we used to hag out after dinner because of the nice weather we had during our stay.
It is wortrh to mention as Chris does in his presentation that there are several stairs to the flat despite of the elevator in the building but this was ok for us even if we did go out with a stroller every day. No big deal, just seven stairs in the basement and around ten to get from the lift to the flat. practicable.
the apartment had also some stuff that came in very handy such as washing detegent, tablets for the dishh washer, shampoo and soap, an expresso machine and salt, sugar and other condiments that are sometimes a pain to get for such a short stay and you are so happy to find.
Overal, will definitely go back again when we visit Vienna.
