Pros:
[1.] Amazing location. Seems like just a few steps away from piazza del Duomo. We were able to do everything on foot, which was great.
[2.] Lots of restaurants and places to eat within a short distance. Lots of stores to shop at as well.
[3.] The size of the apartment is quite nice.
[4.] One of the hosts is a very sweet woman, and we loved meeting her.
[5.] The apartment is front-facing and you get a view of the street.
[6.] The fridge is big and fits food, big bottles. The kitchen has cute yellow cabinets and many utensils.
[7.] We loved that there were recommendations of places to eat by the hosts
[8.] Hosts provided a few wall adapters to use. That was a super nice touch and showed that they care for the experience of the people they host.
[9.] The hosts also made themselves available over Whatsapp for any questions or concerns.
[10.] Big plus: the hosts actually worked with us to get us in as soon as possible. We hadn't decided yet when we were going to take the train to Florence. They were flexible with us and we really, genuinely appreciated that.
Also of Note:
[1] The apartment belonged to the hosts' family and is older. Expect old furniture passed down through generations.
Cons:
[1.] The only downside of this apartment was really that the windows did not block sound from the outside. During nights the noise got pretty intense at some points. But seeing as this is a really old building, and the windows are very tall, I understand that this is just the way it has to be.
