This is a decent B&B run by morally corrupt people who are more interested in profit than people. We were promised a "beautiful room overlooking Rome! but unfortunately the owner sold the room to other guests for more money and then decided to create a huge lie that we had received the room he had confirmed in writing NINE MONTHS earlier. Airbnb refunded us the money from Matteo in adjudication.
In addition, the reception manager charged us a city tax which was not mentioned on their Airbnb listing. This was explained on check-out but her sneering arrogance got the better of us - Airbnb got this €14 refunded too.
This sums up the customer service in this hotel/B&B - money first, clients a distant second!! I also observed the manager chastise a waitress for serving coffee to a guest 3 minutes after the breakfast deadline - shocking behaviour!!
Great location but I cannot recommend Navona King/Queen for the general experience and the poverty of their customer service. AVOID, AVOID, AVOID!!!!
