Erich was a fantastic host: he was very helpful via email before our stay, and went out of his way to make sure we could check in at a very inconvenient time. The apartment itself is in a dream location, right in the centre of everything you want to do in Vienna. It is more spacious than the pictures suggest, and has all of the basics - and some of the frills too, like a proper iron and ironing board. An excellent stay.
