For those driving in from the airport: Set your Google Maps app to "Harpa" (the new concert hall venue). Once there, then re-set to the Canopy. This will get you around the current construction, that has the street closed in front of the hotel, and to the parking garage next to the hotel.

If you don't do this the Google Maps app will be constantly re-directing you to turn down streets that are closed to car traffic for the summer tourist season. I don't know when those temporary closures end.
