This place is so cool. We are parents traveling with late-teen / early twenty adult kids. The interior is ultra-modern European. The private outdoor courtyard is perfect for breakfast or happy hour conversation. Nice kitchen and bathrooms.
Location is very nice. Restaurants downstairs with a locally popular cafe next door. Second-best gelateria in Rome is across the street (a compliment - there are so many great ones everywhere).
Location: Very close to many sights, with a short walk to Spanish Steps, Trevi Fountain. Around the corner from shopping district, including fashion, two official soccer team stores a coop market (local grocery). Check-in was easy. Check out painless.
One issue to consider is that a flight of stairs is required for entry.
