We were two couples traveling together, and so needed two separate bedrooms and two separate bathrooms. And we needed it for a week. Spaces like these are not easy to find, especially in a place like Florence.
Chiara's apartment seemed to meet our requirements (you can never quite tell from a description), so we went with it. In this case it was exactly what we needed.
Location: It is around the corner from the Accademia (think "original statue of Michelangelo's David"), within easy walking distance of Piazza del Duomo, and a block from Piazza San Marco, from which you can take several city bus lines, including at least three to and from the train station. There are at least two convenience stores within a block for groceries.
The entrance is on the third (American fourth) floor of a multi-tenant building. There is an elevator, but be warned, it is tiny. I had trouble squeezing in with our large suitcase. That, and the three or four steps from the street door, would probably make it unsuitable for anyone in a wheelchair.
The apartment itself is on two levels. The entry level has one of the bedrooms (two beds), a bathroom with an open tub and a shower attachment, a well-equipped kitchen (including American-style drip coffee maker, European style caffé maker, microwave, dishwasher, and gas stovetop), and a sitting area with two couches as well as a table and four chairs. The other bedroom (king size bed) and bath (shower stall) is in an upstairs loft reachable via a tight 13-step circular staircase just outside the kitchen.
The bathrooms have tiled floors. The rest of the rooms (on both levels) have beautiful hardwood floors.
There are plenty of electrical outlets, but of course you need to bring adapters if your plugs are different from those used in Italy.
Chiara was there to meet us when we arrived, showed us all around, and pointed out the features and amenities in the kitchen. She lives in the unit directly across the landing from the one we were in.
One incident is the best demonstration of why Chiara well deserves her Superhost rating. The apartment is heated by hot water radiators in each room. The same (tankless) heater also supplies hot tap water. One evening, early in our stay, we noticed a lack of hot water in the taps, and also that the rooms were getting colder. I called her number even though it was after 10:00. She came over immediately with a friend. The heater was brand new. They tried to fix it; when they couldn't, she brought a space heater for the downstairs and activated the upstairs heater. She also scheduled a service call for early the next morning. And offered to move us to another apartment in the building if the heater could not be fixed that day. Thankfully, it was fixed, so we didn't have to move. Brava, Chiara!
