It was my first time of using that kind of service ''airport transfers''. Usually I used regular taxi service that you can find staying right in front of any airport (usually they charge you ''the tourist price'', that happens to be much higher than normal price. So this time I decided to surf the internet first and pre-book a taxi. I was very pleasant surprised that it's no extra charge for waiting if your plane is delayed. The company is monitoring flights, so even if your plane landed earlier, the driver will be in time (and you don't have to pay extra charge for it). Very comfortable I think. Drivers are very polite and helpful. Cars are clean and spacious. I liked this kind of service very much and price is VERY good.
