We spent a few days very pleasant in Elena's apartment.
It is spacious, well decorated and comfortable (kitchen well equipped and bedding very comfortable).
It is located in the heart of the old city of Florence, very close from the Piazza della Signoria and from the Duomo. There are many restaurants and shops very close. The price to pay for this very convenient situation is noise from the street, particularly in the living room. Note that one of the bedrooms is very quiet though.
Many thanks for Elena and Sofia for their warm welcome and their flexibility to accomodate our arrival and departure time.
We highly recommend this apartment.
