This is a lovely apartment in a terrific location with a gorgeous view. You can see the Duomo from the kitchen window, the living room, and the roof terrace off the bedroom. It's the perfect place to stay for just a few nights, or a week, or a month like I did. I highly recommend this flat and am already planning my next trip back.
Elly was so accommodating about meeting me and Francesco made sure that the internet service was fast and reliable. A new awning was just installed on the terrace. It was so relaxing to sit there in the morning and evening, listening to the birds and church bells ringing, and to look out at San Miniato in the distance, Santa Croce, the Duomo, and the towers of the Badia, Bargello, and Palazzo Vecchio. The location is unbeatable - a block to Ospedale degli Innocenti and Santissima Annunziata, and 2.5 blocks to L'Academia. I loved finding some great neighborhood spots including the courtyard of Cafe Fedora (4 blocks away with local prices of 2.30 euros for a cappuccino and cornetto) and the corner wine tasting bar also on Via Ricasoli. One night there was even an impromptu fireworks show from a wedding at the nearby Four Seasons Hotel. Every place I wanted to go in Florence was within easy walking distance.
The rooms are spacious with high ceilings. All the windows are new and well-insulated so you don't hear any outside noise when they are closed. Keep them and the shutters closed during the day to keep out the heat and open them in the evening to let in a cool breeze. There are A/C units in the bedroom and living room. I was very comfortable working remotely from the Living Room and the Dining Room and even the Terrace when it was not too sunny. There's a fully equipped kitchen with a dishwasher so you can cook a full meal at home, or just boil up some fresh pasta (it's easily walkable to Mercato Centrale or Mercato Sant'Ambrogio and there's a little supermarket just 4 blocks away). It was also really handy to have a washing machine to do some laundry. (Note: like in most Italian homes, there is no dryer, but my clothes air-dried on the drying rack overnight).
The only caveat: If climbing stairs is a challenge, this may not be the place for you. It is on the 5th floor (4 floors above the ground floor) and there's a tiny lift (that I only used when I had luggage or was carrying groceries) that goes to the 4th floor (3 floors above the ground floor). In other words, you will have to carry your luggage up one flight of steps. I think the view makes it worth it.
