B&B Ca' Princess, Venice

I have not heard of that one and also didn't find it on Google maps. The only Google result was from booking.com, where you presumably found it; their map places it in a convenient location.

Nope, that's a new one on me. But there are many thousands of places to stay in Venice and probably no one person knows them all, or even most.

What struck me was the name. "Ca'" is a Venetian expression meaning large house and almost always has the name of a family as the second part, or at least a Campo to which it refers.

Princess is clearly an English word. It is surprising to see them together....
