I have tried several times to contact Bulgari Hotel Milano on their WhatsApp account listed on their website to make a reservation for the bar in April 2023. However, at first I get a reply, but every time after that I do not get a reply. I don't know if it was intentional or not, but this kind of problem never happens in other 5 star hotels. They could have called me if it was an error or something, but they never did.
