We had a fantastic stay at this property, the location cannot be beat. It's right in the heart of Rome, the windows open onto the Piazza Navona. The linens and bathrooms were very clean, beds comfortable, and kitchen well-equipped. Very safe and well-lit, doors were secure. Usual quirks with an old building, nothing out of the ordinary for Europe. There is a lift to help with luggage, which was definitely useful.
The host was readily available via WhatsApp. We had one issue with a key not working properly shortly after arriving. The host returned immediately and gave us a new one to make sure we didn't waste any time on our vacation. He also provided us restaurant recommendations for the area, and got us a driver to/from the airport. This made for an excellent family vacation in a city I had never visited before.
Five stars all around -- I cannot recommend this property enough!
