We had a mixed experience with this apartment. The host gave detailed instructions in advance for self check-in but did not respond to messages seeking guidance for reaching the apartment. After reaching the apartment, we called the host to clarify a check-in instruction but nobody responded. Thankfully we managed to check in but if a guest had some problem or emergency I am not sure if the host would respond. The apartment itself is very clean, modern and functional. The AC is a big help in summer but there is only one small AC in the living room so it takes some time for it to cool the bedroom. We didn't find any curtains in the living room which makes the apartment too sunny and hot. The terrace has a nice view but there is not much privacy. In fact when the adjoining terrace is being used, it creates a nuisance in the apartment also. Thankfully, the neighbors were quiet during the most part of our stay. The location is not much to write about. The common areas of the building including the elevator seemed dirty and there was always a strong strange smell in the entrance lobby. The apartment probably is value for money given how expensive Vienna is but our experience was below par compared to other Airbnb experiences we've had in Europe.
