Emi's place is conveniently located near the museum campus and public transport, and also within reasonable walking distance of most of the sights you'll want to see in Vienna.
The apartment is comfortable and clean, and has everything you'll need for your stay. There is also a small elevator in the building which makes it a lot easier to carry your luggage up to the apartment!
There are numerous restaurants and cafes nearby, including a restaurant and bakery in the building complex. We went to Cafe Ulrich which is in one of the walkways on the other side of the street and had a very enjoyable meal.
We didn't get to meet Emi as she was out of town, but her niece Lydia met us upon our arrival and gave us a comprehensive tour of the apartment. She and Emi were both very helpful and responsive to queries while we were in Vienna.
This is a great place to stay, and we would definitely use this apartment again if we returned to Vienna.
