Use this company at your peril. I pre booked a transfer from Belfast International. All seemed bona fide, vouchers received by email, instructions & drivers phone number received on WhatsApp. However the driver was not there & when I called he said he had no record of having taken a booking from Hoppa. Communication with hoppa to resolve this issue was through a bot on WhatsApp, all agents busy kind of scenario, no phone calls to me forthcoming. Had to find a taxi. Shocking service, has the feel of a scam about it. No refund 5 days on.
