Valeria was a great host. I haven't met her, but communication was good through messages. Helpful with whatever I needed. I recommend to spend the 30€ and request the private car, as the site might be quite difficult to reach by other methods (from/to airport). Accommodation might be far away to Fontana di Trevi (for example), but in 15-20 min walking, you are in Coliseum. Apartment is clean and has whatever you need. Shared bathroom wasn't a problem as it was always empty when I needed to use it. Room was clean, with comfy bed. I would recommend this accommodation!
