If you are looking for an inexpensive room close to the train station (7 minute walk) then Fair Suite will work. 20 minute walk to Trevi Fountain, 25 minute walk to Colosseum, 10 minutes walk to some decent shopping, many restaurants in the area, and a good breakfast bar a couple of hundred yards away. The room itself is a 3, but the host, Napoleon and the location move the overall score to a 4.
