Very highly recommended when travelling to/from Heathrow and Cambridge. I've made this trip several times and tried many other car hires, and I've found Airport Lynx to be the best. They offer normal sized cars, MPVs (what Americans call minivans) and even mini-buses for up to 16 people. For a recent trip I had a large group of 10 people with a bunch of luggage that would have required at least 3-4 cars. Airport Lynx provided a minibus which saved us a lot of money and was quite comfortable. Drivers arrive early, are very professional, and loaded / unloaded all of our suitcases. The cars are clean and in very good condition, and offer wifi and even free water. Technology wise, they send email confirmation upon booking, a follow up email when the driver is assigned, and a final email when the driver arrives for your pickup. Signing up for an online account requires a UK phone number, it would not work for US based numbers. However a quick phone call to book my reservation was easy and pleasant. A final note they accept credit cards without a surcharge, some car services add an extra 5% or require cash only! read more
