My friend and I from New Zealand had a very enjoyable stay at Hannes apartment. It is very central to Vienna's transport whether it be train, bus, or cycling. We enjoyed a great day getting around on bikes. Hannes advised us well of where to go. A highlight for us was the choir singing at St Stephens Cathedral on Sunday. Also a trip at sunset to the top of the Sofitel Hotel is a must . Only 5 mins walk from apartment. Also was nice quiet area especially at night. Felt very secure. Many thanks
