O & V has been really awesome, friendly and helpful towards my girlfriend and I. They have a really neat, lovely and beautiful house and no words can describe how much we loved it. We really enjoyed our stay there. The location of the apartment was really near to the centre of Vienna. Breakfast were prepared nicely for us free of charge. Both of them really made us feel so so welcomed. All the facilities we needed were provided. They also suggested on places we can go on our next destination. I strongly recommend them being a host.
