Me and my girlfriend stayed at Silvia's loft while visiting Florence for little more than a week and it was amazing. The apartment is at a great location, every major attraction in the city is on walking distance so we did not have use public transportation or taxis for our entire stay! I have to say the place looks even better in reality than on the pictures. There is a spacious ground floor with a small kitchenette (which we didn't use but it's definitely suitable to cook your own meals there). The bathroom is rather small but this didn't pose any problems for us. The (air conditioned) bedroom is upstairs, the ceiling here is quite low so watch your head. I would recommend anyone travelling to Florence with two people to stay here on your visit.
