I recently used Elife and would recommend them.
I recently used Elife for my transfers to and from JFK to our hotel in times Square. The only trouble we had was on arrival I had no Wi-Fi or mobile data. But I managed to get Wi-Fi and found him. He was very good and responsed to my messages. He'd parked on the car park and not at the pick up point. Our return was absolutely brilliant no problem on time and got us there safely traffic was terrible.
