Peter's apartment is THE perfect location in Vienna's Old Town. Everything you would want to do is walkable. This is especially helpful if you like to shop but don't want to carry all the packages. There are also plenty of restaurants and a grocery store nearby if you plan to use the kitchen. The Herrengasse subway stop is also just 2 minutes away for excursions outside the old town/trips to the airport. The beds were very comfortable, and the bathroom was huge. Plus, the WC is separate from the bathing room, so if you have a group that is a huge plus for everyone getting ready at one time. The place was spotless when we arrived. In short: if you want to spend a lot of time at the apartment, you will be comfortable, and if you don't (isn't that the point of travel?) you will be very near to all the activities.
