Montessori (Belgrade)

Hello everyone, i'm looking for a Montessori school ( and eventually a Montessori nanny ) for my childrens. I think it exist three of them in Beograd but i dońt know if the specificities (formation, material, education... ) are the same here like anywhere else because the price seems to be very low :/
If you eared about it let me know because if it´s not what i expect i'll choose an international school for september.
Thank you very mich, regards.

Zdravo svima, trazim skola sa Montessorim metoda ( i mozda ce mi trebati jedna vaspitacica ) za moja deca. Mislim da ih ima tri u beogradu ali neznam dali kvalifikacije ( formacija, materijal, edukacija... ) su iste kao svuda na svetu zato sto cena mi je nakako mnogo jefnina nasprem sta treba da bude :/
Ako ste culi nesto u vezi toga recitemi, ako nije sta sa ocekivala onda cu izabrati jedna internacionalna skola za septembar.
Hvala vam puno, pozdrav.
