Alessandra is very responsive and helpful as she allowed us to do early check in and with extremely clear instructions to get to the apartment. The place is rather small but just nice for 2 person and it's equipped. Just take note that there's a flight of stairs, so if you have big luggages you will need to take it up that 10 steps.
Location wise is amazing, just a 5 min walk to Duomo and lots of good food, souvenirs and even supermarket just downstairs.
Highly recommend to stay here if you don't mind the stairs.
