Flat is very good located - a lot of supermarkets around. Underground station is very close as well. It took me about 20-30 min in total to get to the city center. Flat itself is perfectly equipped - coffeemaker was my favorite.
Elitsa is probably the best host I’ve ever met - very quick responses and a lot of useful tips.
So thank you very much. If I’m ever back in Vienna i will choose this lovely place.
