We had a great time at Carolina's. The house is beautiful and really well located, also very big and comfortable. As it is right at the city center is not so quiet but nothing that disturbed us. They live at the third floor no elevator but it's Italy, just get used to it.
Carolina and her mom were great hosts. They had all those books, maps and guides to help us. Carolina also marked at a map great places to eat.
We recomend staying there! We loved it.
