First off, Friedolin is an amazing guy/host. We kept constant communication and he was very friendly and available for anything we needed. We had some issues and delays on out travel schedules and although we arrived to Vienna early in the morning, he was very understanding and kind to let us check in in the AM and even leave our luggage after checking out. His roommate is such a nice guy as well and was very respectful and helpful.
Location of the flat is just PERFECT! Seriously! Easy access to the metro U4 (three blocks) and a very nice residential and quite neighborhood.
The apartment is very cozy and comfortable with nice kitchen and bedroom.
