Yes, I've trained at that school but not long enough to rate everything.
Tecnam planes (P2006T and P2002JF) are new and well maintained (the school has its own CAMO). They got a substantial financing from the European Union to buy P2006T so they can and do take good care of it. As far as C-150 is concerned, it's as new as it can be - most likely produced in 1980s. Other planes look good from outside, but I have no knowledge of how they look inside.
Instructors - I've flown only with one of them. Proficient English, good teaching skills, very good knowledge of all plane devices/systems. As far as I noticed, others speak English quite well.
First time passes - no knowledge of practical tests beside my own test. I passed at first time. Theory tests - have a look here

Employment - no knowledge.
If you learn how to fly C-150/C-152 you'll have no problem flying C-172 (1h familiarization with instructor will be enough). Piper Arrow - don't know. Tecnam P2002JF - it has a stick instead of a yoke. Never flown, but heard that 1h familiarization is enough. Tecnam P2006T and Piper Seneca - everybody claims that there is a big difference because Seneca's MTOW (depending on the version but around 2000kg) is almost 2 times more than Tecnam's (1180kg). Never had a chance to fly Seneca, maybe somebody who had can give some input on that.
3 months distance learning course of ATPL (as far as I remember: 550h of self-study) and 10 days of classroom session (10x10h=100h) is possible and real. I did go thru a distance learning course like that (not Bristol though) and passed all my exams in 1 session (yes, one 2-week session). Overall it took me about 5months - 3 months on-line, 10 days classroom + few days to apply at Polish CAO to get password to be able to take tests. ATPL(A) CBTs are organized in Poland every month - currently the last 2 full weeks of the month (usually excluding one summer month - this year it was August). Remember, that you'll have to travel to Warsaw (1h45min by train one way + 25min tram to CAO) to take each of your tests. Of course, one day you can take few test (even all 14 if you feel lucky enough).
My advice would be - gather as much info as you can about contract details (amount of hours on particular planes, who pays for plane rental for your exams, etc.) from all 3 schools you named and estimate your living conditions. When you have all that information - make a decision. Maybe somebody can share info about those 2 other schools you consider.
