I've renewed my MEP-SPA IR a few times with them. Generally, they are OK, professional etc.
The main concern I had with them is that they don't fly in what they deem to be poor weather conditions. My definition of poor weather conditions differs from theirs - they wouldn't fly with 25 kts down the runway and a few clouds.
Schoie - get on the phone to them. The receptionist chick (cant remember her name) knows what's going on, she is generally helpful. However, I wouldn't accept a FB message as confirmation personally.
James - they do indeed offer modular courses.
On the whole, they get the job done for a reasonable price with great groundschool/sim premises. The aircraft (flown the twin-com and duchess there) are not new, but are in fairly decent condition and are maintained well.
To summate, I would indeed go back and use them again.
Last time I renewed I stayed in the Holiday Inn Express next to the airport. They do an aircrew rate if you can show them an airport ID. It's walking distance to the GA terminal and about 10 Euro's taxi ride to the sim building which is downtown.
