The apartment is located on a quiet street in Trastevere, which makes it perfect to easily reach many destinations (centro storico, Vatican, Testaccio) by walking, find lots of coffee places, bars & restaurants in the vibrant Trastevere, but also get a good night sleep. And yes, the beds are super comfortable.
Everything is as described and Eva is very friendly and responsive, I would definitely recommend her place and look forward for my next visit here.
