Chelsea! How wonderful. And Florence - what a treat! Will send a couple of recommendations this evening.
Very jealous of your trip to Chelsea. So many recommendations for Florence, we've been quite a few times over the years. This restaurant http://www.4leoni.it/4Leoni/en/ was fantastic, and had great live music in the piazza. Also, the David is definitely worth all the hype, we go every time and it's more awe inspiring each visit.
