We had a great time in Trastevere the apartment is modern and in a great location. Easy to walk to lots of sites and plenty of great restaurants etc close by.
Downside for us was the bathroom/shower was tiny but may not have been as much of an issue if we didn't have a toddler with us. Perfect apartment for a couple!
We did have issues with the power cutting off and it could be a bit noisy at night but overall we had a great stay and would definitely recommend and hopefully come back again.
