My husband and I spend a few days in Florence as part of our anniversary trip to Europe. The apartment is absolutely wonderful! It's completely renovated, very clean, spacious, the bed is comfortable, the rooftop balcony is epic! The place is located one block from Duomo, there are lots of restaurant and shopping options within a few steps.
The kitchen is fully equipped (although we did not prepare any meals other than making coffee). There is a washing machine down the hall (it's free, but you may be sharing it with other guests), there is no dryer, so plan accordingly for the drying time. The apartment has an air conditioner, we were very comfortable.
Getting there was fairly easy - we arrived at Florence airport, took a tram (20 min or less and costs very little) into the Santa Maria Novella train station. From there it's a short walk 10-12 min. Lodovica met us by the entry to the building (there is no keyless entry), helped us get oriented and had a city map and restaurant recommendations ready for us on arrival.
Great place and wonderful hosts. We'll be back.
