The apartment is spacious, comfortable and extremely well located.
In the heart of Trastevere, the most up and coming neighborhood in the city. Surrounded by fantastic restaurants, bars and more importantly gelaterias. It gets noisy in the evenings, not a huge problem though.
Public transport in Rome isn't the greatest, so we chose to walk across the river and into the center of the city for tours, etc. It took us less than 20 minutes to most major sites. The only site that's a little bit further and more difficult to visit is the Vatican.
Overall, a great experience. Highly recommended.
