We enjoyed our stay at Eva's airbnb in Vienna, where we stayed for 4 nights. The location was great- only a couple minutes walk from the karlsplatz metro station, and right by a tram station. The apartment is walking distance to many attraction in the city center, and we only took the metro to further places, such as the Schonbrunn palace. There were several supermarkets (Billa) just down the block, and close proximity to the Naschmarkt, for fresh produce and such.
The apartment was spacious and clean, and the beds were comfortable. There is a VERY big living room, while the kitchen-if one plans on cooking- is rather small. Even so, we managed well enough (we loved the coffee machine). There are a few stairs when entering the building, and an elevator to the apartment. we had wonderful weather at the beginning of September, so we didn't mind the fact that there was no air conditioning, though they did supply fans, and there are large windows in every room.
Communication with the host was fine, and we managed to arrange a convenient time for us to check in. We arrived before check in and were able to leave our suitcases in lockers until we could check in, but we didn't mind it. Very nice apartment, recommended!
