The accommodation is conveniently located, not far to walk from the Termini station. It is in a quiet pedestrian street with a wonderful pizzeria on the corner with tables outside almost directly under the windows of the apartment.It is small but very clean with a good shower and very comfortable beds. I slept on the mezzanine and that was perfectly comfortable. The bathroom might be challenging if your guests are on the large size!
Sabrina was friendly and welcoming .The flat is in an ideal location to walk to the Colosseum and to most of the sights of Rome. For the Vatican museums we took the metro from Termini station. A great few days
