I have used the meet and greet service several times and never had any issues, you pull up stop, hand your keys over and Away you go, unfortunately my most recent trip to Barecelona was different, the weather was cold/ miserable and I found myself arriving to a locked office door, we waited for 10 minutes before the attendant arrived who was apologetic, I just thought ok these things can happen, however I returned to exactly the same, a locked office door and again waited in the cold at nearly midnight for over 10 minutes, I know it's only 10 minutes but if I pay for meet and greet that's what I expect, if I wanted to stand around in the cold I would have chosen the kind stay, therefore on this occasion my rating must be poor.
