This was a fantastic base for exploring Vienna. The apartment is really spacious for two people, extremely clean, and a short walk to the Stephansplatz metro station, as well as other transportation stops. It's really walkable to all of the places you might like to visit in and around the old town area. There's a Billa grocery store conveniently down the street and a taxi stand just outside the building (we only used that to take a taxi back to the airport on the last day.) The shower in the apartment is also really nice; it has lots of windows and good lighting; and the kitchen facilities are nice. We never had a chance to meet Merlinda in person, but she was very pleasant in our written conversations. Highly recommend this place!
