Hello Oli,
I am just completing my flight training at Multiflight.
The place is very good, got great facilities and a good friendly spirit. You have to remember though that its a flight training acadamy rather than a club, therefore if your looking for an evening round the bar with the rest of the club members you will be dissapointed - tea or coffee only lol!
I have flown with all the instructors there (well the ones that fly the Robin) and they are all really friendly, informative, and certinaly know what they are doing. They make the flying fun which can get very labourous going round and round in the circuit lol! The quality is very good, I went solo in under 8 hours, and will be taking my test at 45 hours.
I would thoroughly recommend you to give multiflight serious consideration I have loved every minute flying there.
Good luck!
