Vienna is very hot in the summer time these days. This apartment is in a great location and is quite charming. It is probably great in the winter. It is not air conditioned (contrary to what is indicated in the listing) and a sign/note on the window said it was broken and could not be opened. If your group is for more than 2 people, you should consider another location. We were prepared for the 4 flights of stairs. Nick's friend, Darko is a cab driver and is very helpful on arrival. We could not stay as the temperature without air conditioning, in July/August was unbearable. Our host allowed cancellation and full refund. The heat wave wasn't his fault, I just wish he had been more forthcoming when I asked, a week before our arrival, for verification of the air conditioning.
