Dario made the check in process very easy - he organised a water taxi to and from the train station for us, and met us at the station to hand off the keys. Likewise, a video was provided so we could find the place.
The location was perfect - a few minutes walk from Piazza San Marco, and close to plenty of restaraunts and shops.
The apartment is on the third floor but luckily there is an elevator for heavy suitcases!
