Our Partners

The Florence luxury apartments QK Costa58 Home Tower are the result of a recent restoration. From historical Florentine residence to elegant, charming refuge. This result was achieved thanks to the long-established experience in hospitality of the brand Quadra Key Residence, combined with the passionate touch of Maria Alessandra Mecacci, the mind and heart of the project. We have entrusted the furnishing and textiles with different ambassadors of the Italian excellence.
We thank our partners, each and every one, for collaborating with us to the realization of our apartments in Costa San Giorgio.
