Francesco's place was super central and really lovely - there were a few hiccups with the check-in as we couldn't access via the digital lock due to electricity issues, but Francesco was very responsive and helpful - we waited about an hour and had a late lunch while he got the housekeeping to come over to troubleshoot.
The room is small, but has everything you need. Note that it is a shared space (my bad, I didn't read carefully) so we had a rotation of 3 neighbours while we were in the apartment but no major issues). The kitchenette is well stocked with cooking utensils, crockery, coffee, microwave, kettle...was a dream just to get some pastries from the many cafes downstairs and have a quiet coffee in the morning at home. There's also a dryer and washer, super helpful. Note that also you will need to carry up your luggage 2 small flights of stairs.
All in all, would recommend Francesco's apartment in a heartbeat, especially if Florence is your base for exploration - 10-12 mins, you're at the train and bus stations and that gets you out of the city. The central markets, cafes, main attractions are literally at your doorstep or 5-7mins away.
Thank you for a lovely stay!
