We stayed here the month of August.
The apartment is comfortable, airy, & a great home base. Upgraded windows let in a ton of light, two-way open, & muffle the sound outside. A/c & all appliances work great. Kitchen has everything you need. Valeria has a fantastic library, beautiful taste in furniture, & nice art on the walls.
His nephew Eduardo runs a bnb 2 floors down and is incredibly helpful & accessible. He even set us up with a guide to show us around the Oltrarno.
Apartment lives large and can accommodates multiple adults. 3 proper bedrooms & comfortable beds.
Location, location, location! It's on a street that makes a triangle with the Arno (parallel to the river) & a triangle with Porta Romana so it's easy to orient yourself in the Oltrarno. San Fernando on one side, San Niccolo on the other, Arno is 6-7min going north, and Porta Romana a 6min walk going away from the river to exit the city wall. Highly recommend walking up Viale Machiavelli to Bobolino Park. If you keep going up the hill, a walk along the Viale Galileo and then down via dell'Erta Canina (the 2nd one takes you through a sweet narrow street with peakaboo views; the 1st is a tree lined road) and back through San Niccolo is lovely and offers killer views.
Cross the street & walk 2 blocks you're in Piazza San Spirito. It's 2min walk from the Boboli. Less than 5min walk to Pitti Palace. 10-15min walk to the Duomo. 10min taxi to SMN train station. There are tons of restaurants, bakeries, shops, & grocery stores nearby.
It's on the top floor; stairs are easy to go up.
Remote work... The building is from the 15th century -- the walls are 2.5 ft thick. This is great for soundproofing. But bandwidth is not strong enough for video conferencing from all rooms. Ended up working in the open dining room, living room, & desk in master. Eduardo was very helpful getting access to additional networks & extenders. Lots of outlets.
