We used Taxi PMI on basis of reviews here on Tripadvisor. Airport to hotel and return. On both occasions the driver was ready and waiting for us. A very nice driver, who insisted on helping with bags. The big advantage is the certainty on price (meter fares can escalate rapidly when stuck in traffic),along with the fact you can virtually guarantee the taxi will be there waiting for you. There’s also option to pay on the website or pay the driver. All very efficient.
