Swansea is a nice airport to train from, pretty quite airspace and easy radio. It's a great place to start training but I always liked flying into Cardiff to get a bit of real world airport experience.
You can't beat the relaxed attitude at Swansea for making life easy.
Typical radio call at Swansea:
Pilot: "Golf-Romeo-India-Charlie-Echo requesting joining instructions"
Tower: "Any Runway you like - Wind strong"
Pilot: "Can I get some fuel"
Tower "Sorted But"
