Jennifer's place is really nicely located; there are a ton of things to see and do near the apartment, and she shared a lot of really good neighborhood tips with us. It's conveniently near public transit and the whole city is very accessible from here. We had a great time in Vienna--one thing to keep in mind, though, is that the apartment is on the top floor, and on hot days, it was pretty uncomfortable without air conditioning. So if you're sensitive to the heat, it's something to keep in mind. Besides that, the place is great and Jennifer is a great host!
