Beautiful comfy bus. Great friendly driver. Very timely. Easy to book from the other side of the world.

1. The first driver was not professionally friendly and did not take time to explain clearly the amenities on the bus (e.g. toilet facilities). There was an automated recording that was barely audible. 2. The second driver who took over should have introduced themself and made a comment on the continued journey. 3. The toilet door was almost impossible to open. Even males were struggling to open it. 4. There was no wifi 5. The voice of the person announcing bus arrivals was very unclear.

We could not understand the driver. We could only understand "cardiff" and "city centre" but then he stopped at the university and made everyone get off. He seemed annoyed and did not stop where we were supposed to.

I thought the trip was good but at the bus station in Heathrow T3 the board advised to wait in lounge until 1min before bus was due to leave. Then it switched to go to platform 9. I walked down there straight away and the bus was pulling out. The driver said my seat was probably free but if it's not then kick them out. It wasn't free so I just sat elsewhere.
