while we have used via toe in many cities around the world, madrid was the only one we were unhappy with. although he was there when we came out of the airport he drove way way too fast. it was hair raising. even my 19 year old son said "doesn't he know we want to get to the hotel not end up dead!"
again, on our return we had the same driving - a 30 min trip from our hotel to the airport took 15mins....down right bloody dangerous! he was driving at 140km per hour in a 90km per hour zone. never again in madrid!
