The apartment is excellent! It is big and spacious. Very cozy bedroom, comfortable bathroom and kitchen with all the amenities (even coffee and olive oil, as well as some wine). But the best part is the living room - it is very stylish with the antique furniture and a fireplace.
And, of course, the location is just wonderful! We walked by the Trevi fountain every day, since it is just in a 3 minute walk, and the Spanish Steps are close by as well. The Barberini and Spagna metro stations are 5-7 minute walks away.
Constanza is an amazing host, always helpful and fast to response!
