This apartment is great for staying 4 to 6 persons comfortably mostly for sleeping. The bathroom is very nice and the shower very big and comforbable, as well as a nice and modern kitchen. It´s very well located and very convenient to go anywhere with the excellent Viena´s public transport network. The Wifi is not very good though (a 4G router), and there is no living room, so the table for eating in the kitchen is just for 2 persons at most.
All in all, the price / quality is excellent though.
