Christiana's place is amazing! Location is great, walking distance to everywhere in Florence, right on the Ponte Vecchio. The view from the apartment is amazing and even better at night.
Also the apartment has everything you could need, and is very clean. Christiana is an amazing host and went above and beyond to help us during our stay. She provided us with a portable crib for our 18mth old son, and even some toys. She gave us great recommendations for food, wine and gelato. And lastly she was able to help us print off boarding passes when we couldn't find a printer nearby.
I would highly recommend Christiana's place to anyone travelling to Florence, especially if you are travelling with a toddler like us!
