This is the place! It is beautiful and though the location is a little touristy, it's touristy for a reason. So central, so charming with great cafés all around for soaking it all in.
I can't think of a detail they overlooked. The book of suggestions was the most complete I've seen (and there is a binder for several languages). The kitchen is petite, but well-designed and appointed unless cooking in is a big priority for you. The light in the apartment is amazing. It can be a little "festive" at night, so if you are a light sleeper, or just a grumpy type, that might be a mild drawback, but it was not an issue for us. It's such a remarkable spot.
Bruno and colleagues were extremely welcoming and kind. Highly recommend!
