We would definitely recommend Albertos apartment for a stay in Vienna! It is a very unique place where you can enjoy art all around you while you are just a few steps away from the famous Hundertwasserhaus. It is super clean, well equipped and has some supermarkets, bakeries and restaurants just around the corner. With the tram in front of the door you can reach Stephansplatz within 10-15 minutes! Communication was super quick and informative. Absolute no complaints!
