Pretty good actually. Parked the car myself in an underground garage at some office building site, took the keys and got on the shuttle that was already waiting for us. YWere at the airport within 7 minutes or so. Also the shuttle from the airport was pretty smooth (yeah I put the bags in the bus myself this time but didn't care) and picked up the car in the same state as we left it. Drivers drove pretty safely (one time used his phone while driving) but no real complaints.
