This place has an excellent location in a unique space (underground with brick vaulted ceiling). The air-conditioning is a cool respite from the hot summer heat and the apartment has everything a traveller needs. It was extremely convenient: a full (but busy!) grocery store was a 2 minute walk away, there is a washer in the apartment, the Duomo and Accademia (home to Michelangelo's David) were both quick 10 minute walks away.
This is an extremely practical place to stay with a wonderful and accommodating host. He gave us great tips for our time here, including suggesting Pisa for a quick half-day trip, seeing the fireworks at Piazzale Michelangelo for Florence's founding day and giving is the "Must-see" list.
Thank you for a great visit!
