My wife and I stayed at the apartment for just over two months beginning in August 2018. This is a nice, comfortable Florentine apartment in the terrific Oltrarno/Santo Spirito area of Florence. The apartment is just far enough away from the historic center to have quiet evenings and many restaurants, but still only be a 5 minute walk to the Ponte Vecchio and a 10 minute walk to the city center. The apartment is very homey with a nice terrace and well equipped with a washer and dishwasher.
It is best suited for a couple since there is only one real bedroom, and clothing storage is limited to the one closet in that bedroom. It can be very hot in August/early September and the only functioning air conditioning unit is in the living room (the A/C unit in the bedroom is not connected). As a result, we had to use the fan at night, which turned into a very dusty breathing experience until we moved large amounts of dust-ridden old magazines and linens from the bedroom into the storage unit on the terrace.
The apartment is OK for three people if the third person does not mind sleeping on the single person couch/bed in the living room and living out of a suitcase. Fortunately, there are two bathrooms, which is great. The second “bedroom” is really a detached 8x12 foot storage room with a fixed un-curtained window, no ventilation and no closet. You also would have to walk across the open terrace to use a bathroom. Even though you can put a bed in it, there would be no privacy from the neighbors and the early morning sunlight. As a result, it is not suitable for 4 total people in my opinion.
On the whole, we had a very nice experience here since it was just the two of us for the vast majority of our stay.
