Anja's apartment is the perfect place to stay in Vienna! The location is great, less than a 5 minute walk from the nearest subway station, and it is very easy to get anywhere you want in the city from there. Anja's friend Esi was great at communicating with us, and she gave us a ton of really great tips for sightseeing, dining, and anything else we wanted to know. The check-in process was as smooth as it could be. I was a little worried that the futon would not be big enough for us (I was staying with my mom so we weren't a couple), but it actually folds out into a very large and comfortable bed, and we had no problems with it at all. The balcony is very large and is a nice place to eat breakfast in the mornings. I would definitely recommend staying here for your visit to Vienna!
