Our trip to Florence was peppered with unexpected flight changes (we ended up having to leave day early), food poisoning, and rain, but we had a lovey place to go home to in Daniele and Clara's. The apartment itself is an economically-designed four-bedroom, and they rent out all four rooms seperately on Airbnb. Some have a private bathroom, two are shared bathroom. I imagine this place would be awesome for a group who wanted to rent it out all at once! It's equally awesome for one room at a time, as long as you're up for meeting other travelers and sharing space, which we were.
Clean, sunny, and perfectally located away from the main tourist areas but a very close walk to everything. There is a kitchen where you can store food and heat things up, although they don't allow the use of the stovetop/oven, so you can't actually cook. But you're in Florence - so why would you want to cook anyways?
This was my second time staying here (I stayed in the same room four years ago) and would stay there again!
They were very flexible and understanding with our unexpected schedule changes, and even checked in over message on how my boyfriend was doing when he fell ill. Either Daniele or Clara will be there to greet you in person when you arrive, and they give you a map of Florence with attractions circled, walk you through nice things to do, and make sure you know what neighborhood to grab a bite in. Clearly experienced and lovely hosts.
