The place is extremely clean and tidy, and very spacious! The location of the apartment is also very convenient as it is 10-15min walking distance to the central station, or 5min by tram. The city centre is just 2-3 stops away when using the metro.
Regarding groceries, there is supermarket right next to the apartment.
Alex, the host, is very polite and always ready to help with whatever he can. I definitely will visit the place again and totally recommend it to anyone in search for a cosy and convenient place to stay while in Vienna!
