This is a lovely stylish little place and I loved my stay here - would return again without hesitation.
You may be limited by the size of the kitchen if you want to do a lot of cooking for yourself, but why would you with so many good restaurants and cafes nearby? And the sofa bed was actually really comfy!I personally had no problems, but if you are a light sleeper you may have some trouble with noise from the nearby flats or the restaurant below at certain times of day.
Perfect for a short stay, I had everything I needed for 3 days in Florence. The location is fantastic and easily walkable to the train station as well as all of the main sites. Very happy to have stayed with Alessandra and hope to do so again.
