We stayed here with our two college-age daughters and there was plenty of room for the four of us. The apartment was very clean and nicely styled. Daniela, our hostess, was able to accommodate an early check-in. She met us at the apartment with keys and cookies! She was super helpful with local recommendations.
The apartment is located about 10 minutes walk from the train station and has a tram stop right in front of it. It is south of Trastevere but in walking distance (cobblestone streets - comfortable walking shoes are key!). There are some small cafes, grocery stores, restaurants, and banks within easy access. (Tip: BNL Bank is affiliated with Bank of America and you can withdraw cash without a foreign transaction fee). Cash is required at many places, so be prepared to carry euros!! We felt safe everywhere in Rome, despite its reputation for pick-pockets.
Finally, a special shout-out to Daniela for helping me in advance of our trip. My daughter who is studying abroad in Rome was having a birthday and sweet Daniela found me a local patisserie that would deliver a cake. She made all the arrangements so we could help my daughter celebrate from far away!! She is a super hostess!
