My friend and I loved staying at Jacopo's Airbnb. The location was PERFECT and the modestly-sized room provided for our every need. Our hosts were quick and helpful in their communications and they provided excellent written resources (both digitally and in the room) that aided us a number of times. The bathroom is nice and modern and the shower is on the taller side (yay for a 6'3" person like me!) so bathing was easy. The art on the walls is beautiful and a welcome feature in the room. The internet was slow (roughly 4Mbps download speeds) compared to what I'm used to at home but it was more than enough for our needs while in Florence. Potentially worth noting for less agile folk or people carrying lots of luggage, the room is on the third floor and only accessible via a couple of flights of narrow stairs. Wasn't an issue for us, though, and I assume it won't be for most others, either.
Overall, this Airbnb earns our highest marks. 10/10, would recommend! The value of this rental is off the charts. Give it a stay!
