My husband and I stayed at Annalisa and Leonardo’s apt in florence for four nights. They were incredibly accommodating including making the apt available a bit early for us. Leonardo met us there and helped with the luggage. He also gave us a tour of the place and suggestions for restaurants in Florence. The location was perfectly central and close to the train station. There are definitely 6 flights of stairs (it’s on the third floor), but they are European flights of stairs so not as many as US. Plus I am 5 months pregnant so if I can do it...! But it is something to factor in. Most importantly the apt was as described, so cute and cozy and very quiet despite being on a busy square. I would definitely recommend!
