Everything went very smoothly apart from the incorrect address on our paperwork for the Restaurant Fuhrich. (The address on the paperwork was for Cafe Central consequently we knew where that was for the next day). The pickup from the airport was an excellent limousine transfer, the food at both Restaurant Fuhrich and Cafe Central was good, and the Vienna card worked well. If I have one criticism it was that the Hop On Hop Off buses were very crowded and at one stage was going past stops because of lack of room. All in all, well worth it.
