This is a well located property just a few minutes from Istituto degli Innocenti and Galleria dell'Accademia di Firenze; the Ponte Vecchio is only 20 minutes away. Via della Colonna is relatively quiet, but does have some traffic through the night, so you might want to bring ear plugs if you are a light sleeper.
The property is good value: compact, but with everything that you might need for a city break of a few days or even a week. The air-conditioning kept the space comfortable throughout our stay in August, when it was thirty degrees outside. The loft bed is accessed by wooden stairs rather than a ladder, so is relatively easy to get into, though if you are travelling as a couple, bear in mind that it can be accessed only from one side. The kitchen is stocked with all the utensils you might need, a spacious refrigerator and, on arrival, a couple of beers.
We were let into the property by a friend of the host, but she was just as helpful and committed to us enjoying our stay as a good host would be: we would happily stay in this property again.
