The most unique thing about this place is location, location, location. Truly one-of-a-kind experience looking out onto the Trevi! There is quite a bit of street noise as expected, but closing shutters and drapes helps a lot. The apartment is very nice and spacious, with two bathrooms which worked great for us.
Francesca was in touch from the beginning, and responded quickly. The one negative experience was her assistant, Andrea, showing up nearly an hour late for check-in, despite us specifying exact timing for our arrival several hours in advance. Other than that, highly recommended.
