The property is very well suited to accommodate as much as 5 or 6 maybe (even though they will charge for that), excellent condition, very good space and amenities, has an "Italian Touch", nice bedrooms, living room and kitchen, good to spend a few days enjoying Florence.
Even though the apartment is very well located, literally next door of "Palazzo Pitti" you will have to walk to get into the northern part of the city, maybe 15 - 20 minutes, but still okay.
The main bedroom is a bit noisy, if they improve the windows to seal the noise it would be great.
You have to be aware that when checking in they will have you pay a deposit and an extra charge on city tax per person/night of 5 Euros the night.
Overall a very pleasant stay.
