Two of us spent two nights at Lorenzo'a place. We arrived late but we had a very warm welcome by Mrs. Anna. Though she speaks Italian only, she tried her best to make us understand everything we need to know about the apartment. She is very helpful and energetic. We didn't meet Lorenzo in person but he called for several times to check if we are good with the stay. He is a very good host.
The apartment is exactly like the photos shown, very cozy and comfortable. You can get everything you need. I love the shower the most! Facing a square with a little balcony, you can overlook the energy of Florence. It's perfect! There is a public parking in front of the building and it's good for us to park the car there and explored the town by foot.
Location of the apartment is good too! Very near to the tourist spots and nice restaurants.
The only drawback was the mosquitos at night... better to have some protection in advanced.
It was a good start of our trip in Italy. Highly recommend this apartment for your stay in Florence.
