Avoid
It's not a real school, advertises as bilingual but the staff are all czech and don't really speak english. One of the rooms had an air rifle (?!) leaning against the wall, and this room wasn't locked when not in use so the children could just walk in. The area outside for playing is just the driveway and some grass, the children frequently seem to fall over on the uneven/loose ground around the sandpit and the driveway and hurt themselves. Even when they are not hurting themselves many of the children seem unhappy and often cry. They purport an atmosphere of healthy living on the website despite the husband and wife duo who run it being morbidly obese, and make nasty comments like "we could just get some Russians to do that and pay them less".
They have been investigated by the Czech equivalent of the IRS relating to operating as a non-profit organisation (which they are not), not registering employees, not paying employees correctly, withholding pay slips, tax avoidance, fraud and so on. They have also subsequently attempted to persecute certain ex-employees for reporting them for these activities.
Avoid.
