La Madrague is literally a stone's throw form the airport, we flew in late, sent word ahead and the receptionist Anna, not only waited for us to arrive, but waited past her paid shift to serve us a brandy in the bar so we could recover from the journey, and gave us a useful introduction to corsica.
The hotel is spacious and comfortable, has a large pool and a lovely garden with plenty of comfortable seating.
The room was fine, with a comfortable firm bed and a good shower.
There is a sauna but it gets booked up and we weren't able to try it, also being April the pool was still being prepared for the season so wasn't ready.
We didn't stay long enough to really get to know the place but if you want somewhere close to the airport, this is a very good choice.

The location is great, just 5 mn by car from the airport. The free shuttle service is a real plus, and very easy to arrange. Staff was friendly and helpful, and replied quickly to emails and phone calls.
On the minus side, we thought the room was under the standard of a 3-star hotel. No air-drier in the room, and the aircon remote control was broken. However, to be fair, the receptionist helped us solve these 2 problems swiftly. In the room and bathroom, some small details were not 100% functioning: one plug by the bedside was broken, for example.
In summary, this hotel is great for early or late Bastia Poretta flights, I would just not recommend it for holidays.

Nice place and rooms. Lady in the reception was very servicemined. Must be considered as an airporthotel - far away from any town center.
Service in poolbar/restaurant was appalling. We ordered 2 beers. One got served after 15 minutes and the second did not get served at all. Because of this we desided to eat dinner at an other restaurant.
