No matter where you choose, it's important to ensure that you check out the following factors:
1. The reputation of your prospective instructor (is he/she well regarded in the industry or just in his/her mind - the flight training industry is full of prima donnas);
2. The current PASS RATE for recent students taking CPLs and IRs (and no, a partial does not qualify as a first time pass);
3. The state of the aircraft you will be training in (serviceability is the main bugbear with older aircraft and especially smaller operators - note here that Multiflight has its own maintenance facility);
4. The focus of the establishment and its staff (are they concerned with your training as their no.1 priority, or do they have a host of other sideline aviation interests);
5. The financial state of the organisation (does it look solid - like the aircraft, the state of the facilities can be telling);
6. The morale of other students (busy/motivated or lethargic/disillusioned).
It's important to do the research, because the quality of the training and the pleasure or otherwise, of the experience, will follow you for the rest of your career.
Good Luck.
