We had an awesome stay at Thomas's apartment. It's supremely located near the Belvedere Castle, Karlsplatz and the main train station - just too cool. Thomas welcomed us personally and showed us around including the breathtaking rooftop terrace. Thomas was super kind and responsive, as well as flexible with check in and check out, we absolutely felt very much at home. We were 4 people traveling and the apartment was surely the right size for us, usually preparing breakfast (a supermarket is just around the corner - or even a small farmers market on Saturday). All in all: excellent host, excellent apartment - and a wonderful experience. I surely hope to be back soon.
