I've flown out of Bastia (
Aéroclub Bastia Saint Exupéry) a couple of times with my relative. The club has a couple of PA-28's which are in good shape (149 euros ph). I can check with him if you want more info as the link to the site is in French.
Corsica is beautiful from ground, sea or air (but i am part Corsican so biased). The ATC is interesting sometimes as I think they do training there but quite relaxed so long as you stay out of the military airbase zone (obviously) further down the coast and live fire range. Good English as they are dealing with flights from all over Europe.
On one flight, we flew around the island from Bastia to Ajaccio (a little over an hour) had lunch at the Aeroclub d'Ajaccio (busier airport, transfer minibus from the GA zone to the club but good food 2 years ago) then continued up the coast, meandered by the Monte Cinto (highest mountain on the island at 8,800 feet) and back to Bastia landing between a pair of Airbuses.
Let me know if you want more info and I can check with my relative and contacts who fly there more regularly.
