As previous reviewers have already commented, you do need good earplugs to stay here, if you are a light sleeper. This is worth the investment though as the location is perfect (5 min from the Duomo, 2 mins from the Casa Martelli, opposite an amazing food court and 5 min from the Santa Maria Novella station) and the flat is completely newly furnished and stylishly decorated.
Laura and Giulia are super attentive in their communication and will make sure you have everything you need.
