Rossella has a marvelous place in a quiet and calm district near the Vatican, which was greatly connected with the city center by public transport (3-5 minutes by foot to the nearest metro station). The apartments are clean, cozy and bright and provide total privacy.
Rossella was amazingly friendly, responded quickly to messages and helped a lot with tips about local and tourist areas.
I would highly recommend this accommodation as a place to stay during your visit to Rome!
