I traveled to Florence from NYC with my husband, our baby, and my mother. The hosts were helpful and responsive at all times before and during the trip. They helped us figure out transportation to/from the airport, made reservations for us at a popular restaurant for Florentine steak, and gave us good recommendations whenever we asked. The location is good--though not in the dead center of the city, there are great food options nearby and nothing we wanted to do or see was more than a 25min walk away.
The space is really beautiful. It has been renovated with high quality materials, and this was easily the most well-appointed place I've rented through AirBnB. The marvelous Dr. Vranjes fragrance that greets you at the entrance is so welcoming, and the basket of pastries really came in handy for a hangry baby a few mornings. The pack n play provided is much longer than a typical pack n play, and our baby loved it as well as the pillow and blanket provided. The apartment was quiet and we made good use of the washer/dryer and comfortable common area.
The only slight drawback for us, traveling with a baby and an elderly person, was that the apartment is on the 2nd floor (3rd floor for Americans). This doesn't stop me from wholeheartedly recommending Yu and Emilio's place, though. Thank you for a fantastic stay!
