Christoph's place was really fantastic, the location was perfect for us for sightseeing and also for its closeness to the Vienna Marathon start line. The apartment suited our family (we had a 1yr old in tow) and there was room to safely leave the pram downstairs. Everything we needed was there or just on our doorstop. Chris meet us at the apartment and gave us a tour and some info on places to go and how to get around. We had a great time in Vienna!
