Spend 3 Nights in Gary's apartment with a group of 7 persons. The apartment is well furnish and confy for a large group. The street isn't really noisy and everything can be found neerby (metro, bus, tram, supermarket etc.) it's only about 10min to the city center and 20 to the SchonnnBrun castle. Perfect spot to discover the wonderful Vienna.
Gary had been a thoughtful host even if we didn't have time to meet (there's a lot to see in vienna!) he send us some messages and call to see if everything was alright!
If you want to visit vienna with a group of friends and families I can only Highly recommend this accommodation :)
Best wishes!
