I stayed one night here, courtesy of my cruise line, the night before embarking on a Mediterranean cruise. I would not have stayed here otherwise.
The room was smallish but comfortable, and classy. The public areas were also nice. The front desk was helpful with currency exchange, as was the concierge with answering our questions.
The location is convenient to the Spanish Steps, and the Villa Borghese.
Breakfast was included with our room, and what a buffet they have! Everything you could want was there, including champagne, and all of it was delicious. I would not have paid the 35 Euro asking price for it, though.
Nice place, but I'm not rich enough to make a habit of it.
