her care and attention to our needs and our vision were second to none, we could not have done this without her.
She is now considered part of the family
Avec un sens du détail parfait, elle nous a proposé de merveilleux prestataires, nos faire-parts étaient raffinés, les lieux de réception magnifiés par une décoration florale sublime, les animations ont ravi tous nos invités par leur originalité et leur élégance.
Nous avons été accompagnés tout au long de la journée par une équipe de photographes et de vidéastes qui ont su rester discrets et capturer l'émotion et la beauté de cette journée.
Grâce à Gianna et à son équipe, nous avons vécu une journée d'amour inoubliable !!! Love.
