Lia's apartment is gorgeous - just as described. The location is amazing - close to so many sights. We walked to everything - Pantheon, Trevi Fountain, Colosseum, Vatican, Spanish Steps, and of course Piazza Navona - all between 5 and 30 minutes.
The three of us were quiet comfortable (one adult and two tweens), and although the place is small, it was roomy enough that with the air conditioning it we could rest and read in the hot afternoons.
The neighborhood, building, and apartment are fantastic. Lia is responsive and quite accommodating. High recommendations! Definitely would stay here again.
