Really easy to book on Viator. There's a courtesy phone next to the ground transportation desk. We called them up and they told us the pick up point, and the car was there within 10-15 minutes. We would use this service again.
I paid about 50 for this which is already expensive considering gett and uber is a lot cheaper...
the driver at the end asked for tip which i did not like. the website did not even tell me about tipping the driver...
the car was nice and the driver was nice too but that tip thing put me off this company and also the price.
Driver arrived a short time after our phone call requesting pick up. Safe, courteous and efficient service. Would recommend.
