We decided to honeymoon in Florence and stayed in Enrico and Paola's apartment. They were easy to reach and helpful.
The apartment is small (as we expected from the description) but cute and very clean. They left wine for us which was very sweet.
It's a comfortable apartment, although the bed could use an upgrade (the wooden slats under the mattress fell through a few times), and several of the windows were under repair (ie: boarded up).
The bathroom is small but pretty modern with a nice shower.
The apartment is in a great location - very central and easy to walk to everything. We walked all over and loved it.
We did stay here in the winter, and so the noise level was not as high as we'd read about from the reviews of people who stayed here during the summer, but it still is definitely a bit loud, being off a relatively busy street and right above a popular pizza place. It worked for us, but if you are sensitive to noise, than it might not be the right fit.
We would definitely recommend this apartment for a couple or for a single person. It would be tight with more than two people, (a third person would have to sleep in the living room/kitchen) but it was perfect for us.
We'd feel confident staying in one of Enrico and Paola's apartments in the future.
