Be sure to visit the Westin Excelsior Rooftop! It's one of the best views of the city (aside from Piazzale di Michelangelo). If you're looking for a soft and amazing Italian leather shop, with the owner who does all of the design and adjustments in-store, check out Buti. My wife and I love our jackets and they look and feel amazing! From what I read on google, his purses are fairly popular as well :)
