Marie-Therese was such a wonderful host. Upon arriving she showed us on a map all the main sites to see and some very nice places the locals like to go to eat, drink and relax. She even showed us the places not to go (for safety reasons or because there isn't anything worth seeing).
The apartment was great, very well decorated and makes you feel right at home the second you walk in. Very clean and comfortable feeling. It is about a 10 or 15 walk to the city center, not bad at all. It's in a quieter neighborhood with some great restaurants, bars, and cafes. A few minute walk to a metro station if you want to get around using that. Overall I would highly recommend staying here if you visit Vienna.
