Me and my wife spent nearly a week in Rome in this tiny but nevertheless very cozy and stylish apartment. Lis Mari is an extremely helpful and kind host, she has thought through every single detail to make your stay comfortable.
We really liked the location - it is not a loud touristic area, but still it is very close to main attractions. We enjoyed walking to Vatican city and Trastevere, but if you don't feel like it - bus and tram stops are just nearby. Park in font of the apartment is awesome - you can get a "picnic package" from a caffe just inside the park and spend the day just lying on the grass under the sun.
