Bartolini?
No VAT.
Low costs.
No landing / approach fees.
They have their own sim which they charge out at very reasonable rates which you will use for the majority of the IR.
The hourly rates on their Tecnam twins with G1000 are significantly less than the hourly rates on the traditional twins used by most schools.
There are no examiner fees (they use industry examiners rather than costly CAA examiners).
The whole process is quick - 2 months for the complete CPL/IR course vs 4 to 6 months at most schools - keeps costs down for everyone (but you do have to work hard!).
Accommodation is cheap.
They are nice people.
No link other than as a happy customer. I've got no experience of other EASA CPL/IR schools so can't really make a comparison ......
