Good morning! Welcome to Hotel Nazionale.
ben-ve-NU-to — four syllables, stress on the third.
This is what the receptionist says to greet you. Knowing this phrase helps you understand the greeting and respond appropriately.
'Benvenuto' (welcome) agrees in gender and number with the person being welcomed: benvenuto (m. singular), benvenuta (f. singular), benvenuti (plural). 'All'Hotel' = 'a' + 'l'' contracted before 'H'. The response is typically 'Grazie' or 'Grazie mille'.
Grazie, è un piacere essere qui.
Thank you, it is a pleasure to be here.
A warm response to the welcome greeting
Grazie del benvenuto.
Thank you for the welcome.
A slightly more formal acknowledgement
Buonasera, siamo felici di essere qui.
Good evening, we are happy to be here.
Use 'siamo' if welcoming on behalf of a group
Italian receptionists typically use formal 'Lei' address with guests, not 'tu'. The greeting style is warm but professional. Using 'Lei' in return (rather than 'tu') is correct etiquette when speaking with hotel staff.
