Manfred's place is clean, modern and amazingly spacious. Very comfortable for 4 adults, 2 large bedrooms, both with king-size beds and room darkening electric blinds. Lots of windows with a great view of the unique Hundertwasser House with its quaint little mall. 2 well-stocked markets, both within a block of the apartment. Self check-in was very easy, with clear instructions from Manfred. The building was secure and we felt very safe. As noted by others, the 3 flights of stairs may be a challenge to some but we who are into our sixties managed just fine. The climb was well worth it.
