We loved our stay at Modestino's place.
The apartment is enormous and very very stylish. The outside deck is a wonderful touch as well.
Everything worked perfectly well.
The only thing is that the wifi was a little weak at times. It worked well on my laptop but I had trouble connecting with it on my phone.
If you're a student covid refugee and you still have to take online classes, this might be a bit of a problem. If, on the other hand, you're in Florence for touristy stuff, then this place is perfect for you. Ideally located and very beautiful, I definitely would come back !!
