We (family 2+2) spent 3 nights in Vienna and stayed in "Cosy Nest with Netflix".
The apartment was not too bad. It was equipped with a washing machine, refrigerator, dishwasher in the kitchen (but shortage of cutlery), WIFI , TV with Netflix and amazon prime, and an interesting solution with a bed under the ceiling in the sleeping area (variation on a double-decker bed ;) ).
A bit dirty and with small defects, but I find the time spent in it with my family satisfactory.
The neighborhood is quiet, there is a nice church nearby, but it is being renovated. Flat is close to a shopping center, cafes and restaurants, and there are 2 metro stops nearby. This apartment will be even nicer after repairs and refreshing the walls.
The contact with the hosts took place mainly on-line, they responded quickly and efficiently to messages. Very nice people.
My family spent nice time in Wien, and in this apartment.
