Dan was a great host, who met us at the apartment with the key and showed us around. He was very accessible via phone and internet. The apartment is very spacious, even for two adults, 7 year old and toddler and absolutely central to all Vienna's highlights and public transport. We were very comfortable in the big double bedroom with our kids in a porta cot and single bed, not at all cramped. Recommend getting the Vienna weekly travel card (14 Euro) if you arrive on a Monday, you stamp it once and then can travel for 7 days on all transport except the tourist ring tram - the number 1 or number 2 from the apartment will easily take you around the city centre, and line 4 just five minutes walk from the apartment takes you to Schonnbrunn palace and Tiergarten Zoo. Dan thoughtfully supplies maps and tourist information in the apartment. Thanks so much for your hospitality, Dan.
