We had a blast staying at Sara's charming Trastevere apartment. If you want to have the best food and nightlife at your doorstep you found it. Located just across the bridge from Campo de' Fiore, it's walking distance from all the touristy sights. Apartment itself is spacious, comfortable and clean. It had everything we need including towels, bathing products misc things for cooking like oil, salt, tea/ coffee. AC also was a saver from the summer heat.
The only drawback I might see for somebody is as others already mentioned - a bar with live music downstairs that is quite rowdy until 1-2am. But hey you are in Trastevere!! It didn't bother us, so give it a try and you won't regret!
