Absolutely perfect location - meant that all Firenze has to offer was within easy walking distance. Old building, but great modern loft-style renovation inside, with all mod-cons and super clean. Only issue is the fact there's only one window, so not a lot of natural light.
Didn't get a chance to meet Mariangela in person, but she was amazingly responsive via email, and her colleague Sara was on hand on arrival to show us around everything we needed to know about the apartment.
Overall, highly recommended and big thanks to Mariangela who was awesome to deal with!
