This is a nice ground floor efficiency studio apartment around the corner from Trastevere. It is close enough to restaurants and bars for easy walking access (5-10 minutes to near side of Trastevere), but far enough that the evenings are peaceful and quiet. The apartment is also a reasonable distance to the tourist sites of Rome, particularly Piazza Navona (15 minutes walk) and the Pantheon (20 minutes walk). It is maybe a bit far to the metro/train (about 25-30 minutes walk to San Pietro Station), but bus access is easy.
It is dark outside of the apartment in the evening, so be ready for that - But this is a great little apartment for access to the center of Rome. It is a great alternative to over-priced hotel rooms and offers air conditioning, which is becoming increasingly important to have access to. I recommend this for longer stays, work stays, or leisure for solo travel and couples. Raffaele (the owner) is very nice and helpful!
