Andrei was most welcoming from the time of our booking in Dec 2014 and throughout our stay. He is efficient and experienced in the hospitality industry, and it shows!
The apartment was exactly as described, and was clean and contained all that was needed for the 11 days we were in Vienna.
The apartment is located in the 2nd district, walking distance from all the sights, and has public transport and supermarkets handy.
A secure car park in the building was available, at an extra charge, and this was wonderful in a city where parking space is at a premium.
I have rented apartments in Vienna before, but Andrei's stands out for it's quality. I would definitely recommend this apartment, and Andrei as a host.
