Walter's place was AMAZING. Not to mention Walter himself! He met me at the flat on arrival, showed me around, gave me allll of the info I might need on the area and Florence in general, and all-in-all was just a truly lovely fellow.
I stayed for 6 nights in mid-late December. Just one of me, so there was plenty of space. Two would work as well, if you can sleep in the same bed. More than two, and I'd stay elsewhere. Just my two cents on that.
It was cold. The flat is in an old, beautiful stone building, which holds the chill in well! The inside temp was steadily 60-62° F (~16° C). There was a space heater in the study and a wall heater in the bedroom, but bundling a bit inside was a must (for me, at least). Not a problem, but definitely a thing.
That said, the place was well worth it. With an eccentric aesthetic, a full kitchen, a super comfy bed, and lots of thoughful touches, it was an amazing home away from home. There were more guidebooks for Florence, and Italy in general, than one could possibly hope for. There was info on all the big museums and what not. There were tons books to read, and so many interesting knick knacks to look at and appreciate! The location is fabulous, close to anything and everything one might need. (And more! It is a big city, after all.) All of the sights are an easy walk away, but the flat itself is in a quieter part of town. Good food close by. Beautiful and calm piazza right around the corner. Couldn't ask for anything more perfect.
I am so grateful to Walter for the amazing stay! I would absolutely stay here again, and I highly recommend to anyone considering it.
