The flat looks even better in live than on the pictures. It's very nice, quiet and comfortable. Also it's located very close to the city center, so the road will take max 20 minutes by tram. If you take a look around u can find some supermarkets, Cafe, sweets manufacturer with its shop with lower prices nearby. I'd surely recommend it to my friends and to all who want to visit Vienna.
p.s. Marijan, thanx for your help and tasty coffee.
