This is a very cool place in a bustling part of Florence with quick access across nearby bridges to the Uffizi, the Accademia, the Duomo and other points of interest. There are very good restaurants in the piazza Santo Spirito literally 40 meters from the front door.
The space is really old and historic with up to date amenities. There are 3 bedrooms on the main floor and a small bedroom and bathroom up a flight of stairs (note that bathroom is really tiny....). The walls & ceilings are decorated in 16th century style, there is a garden view out the back bedrooms and the terrace right off the kitchen is space enough for 6 adults The furniture is comfortable enough for average sized adults. The beds are very comfortable.
Elly is a great host. She met us as we arrived, accommodated an early check in, gave us a quick history lesson on the flat and the neighborhood, gave us a map with lots of local advice on where to eat and things to see that Rick Steves may have missed. She was quite responsive during our stay and even helped us find a restaurant on the fly as we wandered around the Mercato. As we departed she helped us get a van to the airport.
Highly recommend both Elly and her place. When we come back to Florence this will be our first choice to stay.
