I had a wonderful stay at Giacomo's apartment! The decor was lovely, and the location is perfect- on the quieter side of town, so close to Santo Spirito and Pitti Palace, and such a quick and easy walk over to the city center. You can hear a bit of street noise, but being from NYC, that didn't bother me.
Giacomo was so accommodating with both my check-in (I was a bit delayed due to traffic) and check-out (he graciously allowed me to leave my bags until my train a few hours past check out).
And the apartment is pet friendly! My pup had a wonderful stay as well. Highly recommend!
