Transfer airport to Barcelona city and return. Inbound was seamless. Return journey… driver arrived roughly 15 minutes beyond scheduled time. Not a major issue as there was plenty of contingency build into the timing but, when we the client have been asked to be at hotel collection point 15 minutes before scheduled collection time it is more than a little irritating to have to wait 30 minutes to be picked up. Especially when a couple of local taxi drivers offered their services advising price would be the same as we had paid. Quite appreciate that might well be the case but, having prepaid, nit really an option. Killer, though, was no acknowledgement or apology from driver that he was late. Sloppy service
