This was a wonderful experience. The communication was excellent and the property manager Mamta was helpful and gave useful info, as we traveled on holidays. She spoke perfect English.
Read all the apartment info well and there will be no surprises. Yes, there are many stairs, this is typical of European apartments. The kitchen had the amenities needed - multiple types of coffee makers, plenty of utensils/plates and a dishwasher.
There's a cute balcony, big enough for 2 people to enjoy the cafe table. Mosquitos are common in Florence, even in December.
The overall cleanliness was very good, especially in the bathroom, bedrooms and kitchen.
Location-wise, it is easy to walk to the city center, restaurants, the river, and shopping. We didn't have a car.
I do recommend this property.
