Angelo's place is amazing. Location is ideal -- located steps away from everything you need (shops, bars, square, market, etc). Centered so that you're 10-30 minute walk to every popular attraction (Colosseum, Vatican City, Trevi Fountain, etc).
The apartment itself is very clean, organized, and cozy. AC if you need it. The unit is located on the 3rd floor walk up, after 2 flights of stairs. One minor this is be sure to bring/buy shampoo. We were provided with clean towels, body wash, and bar soap.
