We had a great experience staying at Sebastian's place! He was so helpful in his communication and in giving us detailed directions to his flat. We found everything to be exactly as pictured/described, with plenty of space in the private room for three people. We did not have a car, so we used public transit to get downtown (which took about 45 min), but we enjoyed getting to see more local life than we would have if closer to the city center. Sebastian was a great host and even offered to let us keep our bags at the flat on checkout day if we were not planning to depart until later. All in all, it was a great experience and I would definitely stay at Sebastian's again. Thanks for a great first visit to Vienna!
