Sophie is a great host. She was quick to reply, accommodating and provided easy directions to her place. The apartment was listed as instant booking, so the process took just a few minutes. I can't think of a better location, which was less than 10 min walk from Metro and all the Museums. The apartment looked exactly as pictured in the listing and was impeccably clean.
I can't thank Sophie enough for being such a wonderful host and I only wish I could stay longer in Vienna.
