Silvia's apartment was lovely and peaceful. She has it beautifully decorated. My favorite part was the bedroom skylight! Silvia was responsive and very accommodating. The location was excellent for me. I walked everywhere that I wanted to go, generally within 30 minutes.
Make sure to visit Santo Spirito, right across the square. It's beautiful inside! The Boboli Gardens less than 10 minutes away was a well spent morning of leisurely strolling before catching my train.
If I was in Florence again, I would certainly stay at Silvia's.
