Claudia's apartment is in a great location, just a few blocks from the Santa Croce and Arno River. She gives great attention to detail, and the apartment is decorated nicely. She was quick to respond to our inquiries.
The only disadvantage for some people might be the 4-story climb to get to her apartment and its small size. This is especially a consideration if you are out of shape, you have bad knees, or it's really hot outside. I'm fairly tall, so I felt a little cramped in the apartment. However, I'm sure this is fairly common for apartments in the older sections of the city and is totally out of her control. If you are all right with the slightly cramped quarters, then it's great!
She has a wonderful balcony (one of the advantages of living on the 4th floor). This balcony serves as her living room.
She also has a small air conditioner installed above her door in the kitchen area, which was a life saver for us, it was very hot when we were there. We had to keep our bedroom door open in order to keep cool. This would not be a problem any other time of the year.
