Depends on the point of origin. Italian cities that could trade with Egypt were allowed extraterritorial merchant enclaves called fondachi in Italian, which is an Arabic word that is used for hotels today. The communes of Italy had sets of laws to govern the conduct of merchants here (an early 15th century lawbook from Genoa makes it very clear that they weren't to sell wine to the Egyptians). They probably wouldn't be allowed to go further than the walls of the fondacho. There's a book about them by Olivia Remie Constable called Housing the Stranger.
