It’s in a historical building in the Oltrarno, on the other side of Arno, short walk to Ponte Vecchio and historical center. Very spacious, clean, and well maintained. Bed and bathroom are upstairs loft style up a narrow stair. Shower was modern and reliable hot water. Washing machine was a nice plus. Fully equipped kitchen which we just used for some coffee.
There is fast reliable internet which was much appreciated.
The only reason I took off one star was mattress was very soft which did not agree with our backs too well, but that may be personal.
Tip: go to restaurant Signorvino, a few steps from the apartment. They have a terrace overlooking the Arno. Also, they have a huge wine store. You can pick a bottle and drink it on the restaurant, same price as faking it home.
