I'm travelling to Florence on April 20 through 24 with a group of Scandinavian 13 year-olds.
The days are planned with visits to a school (interchange with Scoula di musica di Fiesole), a concert where the kids will perform and "general" sightseeing.

Just wanted to check if there is anything "special" going on in the city these dates; Concerts, performances, sports etc? Preferrably at a limited cost (or for free).

Thanks in beforehand! //Cecilia
