Very easy to book and use. Directions to the car park (Birmingham) were clear and easy to follow and transport from the car park to the airport was quick and easy. Would definitely recommend. Only downside was that there was nothing on the website when booking that told you how long a window you had to collect the car once you returned. As we were supposed to arrive late at night (around 11pm) I booked the time to go into the following day. The return flight details only appeared once we had processed the booking and our flight did not appear, only the next flight due the following day. Didn't really make a difference but we could have saved a little bit of money doing this.
