Absolutely loved the apartment. It was perfect for us. I was traveling with my mum who stayed downstairs on the sofa bed and had access to her own bathroom. And I spelt with my 8 month old son upstairs in a big bed and we also had a bathroom there.
The location is fantastic. Right near the Piazza Navona and walking distance to other sights (Trevi, Pantheon and The Vatican).
It was close to a busy street full on restaurants, ice cream places and other shops. The buzz was great! A tiny bit noisy in the evenings but nevertheless my son slept without waking up or being annoyed by it. And neither were we.
Would definitely stay here again.
