I was 3 days in Vienna with my parents and the apartment was perfectly corresponding to the description.

the location couldnt be better than that. You are in the center in a bit more than 5 minutes walk. you can do pretty much everything walking.

I never met Dan as he left the keys in the shop downstairs but everything went fine and if something was missing like a duvet or a second pair of keys Dan brought it to the apartment really quickly.

I really recommend to stay in this apartment if you go to Vienna.
