My husband and I stayed 2 nights in Lucia's lovely apartment, which was a 7-min walk from Firenze SMN station. Once we made our way up the 3 flights of stairs, the San Lorenzo Duomo views from the bedroom and historical parts of the apartment were amazing and the place itself felt very comfortable.
Loved the little touches to the place, including slippers and soap for us. The place was spotless and Lucia was super helpful in getting us settled in despite her basic English - we understood her just fine and she answered all our questions well. She sent us very detailed information prior to check-in and it was easy to understand too.
Location-wise, Lucia's place is excellent. Within a 5-10 min walking distance to a handful of landmarks (including the huge Piazza del Duomo of Florence) and a grocery store, not to mention right next door to Mercato Centrale, where we found a huge range of eats and fresh produce to choose from.
We'd definitely come back to Florence and stay here and wouldn't hesitate to recommend to others as well!
