Looking for garages between Nice and Monaco.

Good morning Europe,

I was wondering if anyone knew any nice car storage facilities in the Nice or Monaco areas or inbetween?

I'm looking to store two Ferraris and maybe more cars in the future. I would be accessing them every three to four months.

I know there is an awesome facility in Berlin with services called Meilenwerks and I would love ot hear there is something similar in the South of France.

Any guidance would be greatly appreciated.

Thanks,
