Elena is an excellent host, very amicable, personable, and has a lot of great advice about Firenze for those staying at her place. Her place is clean and quiet and has a relaxing atmosphere. It's a 30 minute walk from the center of the old city, but the walk is pleasant and along the Arno just one street over. A grocery store is down the street nearby, and if you have any questions about nearby places to go, Elena has good input on a lot of them.
