Mariangela's place is in a fantastic location, particularly if you're traveling to and/or from Florence by train. The walk from Santa Maria Novella train station is less than five minutes -- and it's a beautiful walk by the Santa Maria Novella church and the Piazza of the same name. Walking from the apartment to many of the highlights of Florence (particularly the Duomo) is easy and quick. None of the major sites are more than a 15-minute walk away, and most are closer than that.
This was a fabulous location to explore Florence.
This apartment was the perfect size for my family of 4. It had all the amenities, including a washer and dryer. It was located on the second floor, it did not have an elevator, which was not an issue for us but something to be mindful of. It was very clean and comfortable, easy to relax in. if you're using both of the actual bedrooms, note that they are essentially separated by just a curtain, so noise travels easily between them. These were minor inconveniences and we were happy with the experience of having such a spacious, clean apartment in such a good location in Florence.
Mariangela herself was also great to deal with, always responding to messages quickly. She was a great and accommodating host. We would definitely recommend this apartment.
