This place is really nice. The view is beautiful of the basilica, and we loved sipping wine after a long day and gazing at the view on the patio. This location is great if you are going to the Vatican, but I will say that it is a ways from the heart of the city (think coliseum, Spanish steps, Trevi fountain); you can access those areas by walking, train, or metro. It also is a 50-55+ euro cost to get a ride to the airport, but our awesome host Antonio helped set up a shuttle service for us. The apartment is located in a residential location, so there are some stores near but not a ton of restaurant options right next door. The host Antonio was so nice-- we were late and hoping to make it to the Vatican before it closed, and he was nice enough to drive us!
Just to clarify, if you come from the train station Termini, you need to take the above ground train to the apartment. The host said "train" but we thought they meant metro, so we ended up getting lost and having to take a taxi anyway.
Overall, great place and gorgeous view/apartment. We recommend it, especially if you would like to be in the neighborhood of the Vatican.
