I thoroughly recommend this apartment. The hosts were so helpful. They contacted us before our stay with useful information so we could be confident of how to travel into central Vienna from the airport. The apartment itself is on a quiet street in a central location, and the rooms face inwards onto a courtyard so it's incredibly quiet. It's clean and smart and stylish and the perfect place to stay while exploring the city. We could walk to many of the sites. I would definitely recommend it to other potential guests. Peter gave us lots of helpful advice about what to see and do. We had an amazing stay in Vienna and will be back. What a wonderful city!!
