Marisol's appartment is really nice and you can not beat the location. When we arrived the appartment was spotlessly clean. Marisol was super welcoming and gave us the best tips to hang out in the city, and helped us graciously when we had any doubts.
The appartment was perfect for us, it looks just as it does in the photos (though the bathroom is tiny; but it's not really a problem). It's a beautiful appartment, right at the edge of the city center and about a five minute walk from everything. It's a great choice for a Florence holiday!
