Sofia's flat is in a great spot; less than a 10 minute walk from the Firenze Santa Maria Novella train station and on a less hectic street with basically no vehicles. There are some restaurants and cafes downstairs but it's not crazy busy. But just walk south down the block and you're right where you start to see a lot of restaurants, stores, and cafes.
The flat itself is small but has everything needed. It's great for a solo traveler and couples. The bedroom is a tiny loft they added, so just watch your head upstairs and while using the narrow steps. But it's got a small kitchen, refrigerator, bathroom, air conditioner (which works well), wifi, and a laundry machine. It's an old building, so you'll need to bring your stuff up a few flights of stairs and get used to things like finding the light switch for the stairwell.
What a treat it was to walk down the street to the corner cafe for a cappuccino and cornetto, then walk just a few more minutes to reach all of the good stuff or to the meeting point for a tour. And Sofia and her niece are so nice and helpful. It was a wonderful experience.
