Valentina’s flat is in a busy, residential/commercial area, far enough away from the touristy areas to be interesting but close enough for all those things to be convenient. The Coluseum is a 10 min walk away as is Piazza Della Repubblica. There are several very good restaurants within a 10 min walk. We ate at Central Market in Termini a couple times and were never disappointed. We had a tremendous meal at Ristorante Allessio one evening, as well. There are a couple nice bars close at hand, as well.
The flat itself is pretty spacious and well decorated. The kitchen is well stocked and the beds are comfortable. Valentina was very responsive to any issue we might have had.
