We stayed at this property in the middle of a three week family vacation (2 adults, 2 teenagers), and it was definitely our favorite. It's central location, the wonderful view overlooking the plaza (and yes, the high-quality windows do block out sounds from the plaza if desired), and the pleasant furnishings were all a treat for us. It was our oasis from the heat of Rome, a place to recharge for the next adventure.
All of the amenities worked flawlessly during our stay.
Barbara, our host, communicated far in advance of our trip and made herself available for detailed questions prior to our arrival. She waited patiently for us even though our train from Florence was delayed 45 min and carefully went through the details of the property and some of the local highlights (restaurants, bakeries, transportation, etc) and advice. She also arranged for a mid-stay garbage collection, which worked out great.
All in all, a great experience - would definitely stay again and highly recommend!
