Boys gang to build (Budapest)

Dear All,
We just moved back to Budapest from the UK and I am looking for my 7 years old son some new friends with native English to keep his English at current standard.
He speaks fluently as he went to school in the UK.

So if you have a child around this age and happy to make friendship with a lovely boy in Budapest, just let me know. I am thinking about having some weekend fun together, bycicle tour, soccer, lego play etc.

Kind regards,
Andras
