My family and I traveled to Vienna for the Thanksgiving holiday week. Our group included me and my husband, our two adult children and my sister and her husband and four adult children. Alfred's flats were absolutely perfect. The photos are 100% accurate and if anything, the flats are better in person. They were super clean and everything we needed was provided -- a real departure from other Airbnb properties we have stayed in. Not only does Alfred provide all necessary paper products (TP, paper towel, kleenex), he also has dish soap and other kitchen essentials and all necessary toiletries included in the booking price. The real treat was the complimentary same day laundry service. Alfred's team provide a laundry basket and we left our laundry daily when we went out and it was returned, clean and folded, upon our return. This is something I have never seen offered through an Airbnb booking. Alfred also has a phenomenal cleaner who came in and made up the flats several times during our one week stay.
The flats themselves are very well appointed with comfortable beds, nice linens and lovely contemporary furnishings. Each flat is self contained with a fully equipped kitchen and private bath, but there is a common entrance into the four separate flats so we were able to have privacy if we wanted it and could also travel between one another's flats without entering a public hallway, as you would in a hotel. There are four flats in total and we were able to comfortably sleep all ten in our party with three in each of the two larger flats and two in the others. Everyone had his/her own bed.
The location of the flats was perfect for us. Easily walkable to the city center and many of the sites one wants to see in Vienna -- St Stephen's, Palace, Albertina Museum, etc. -- but also far enough that the flats are quiet and the street not too loud for sleeping. It takes about 15 minutes to walk to the city center. Public transit is immediately outside the flat (250 meters), if you don't care to walk.
Alfred's restaurant recommendations were excellent and our ability to check in early with Barbara following our overnight flights was most appreciated.
I highly recommend this property for large family group or a business group as the flats can be accessed separately and provide adequate space and privacy for non-family groups.
