We arrived at the Romana Termini around 11 AM and Elena was so kind as to let us check in early. Once we figured out the way to get to the apartment, it was a close 10-15 minute walk to the metro. The metro lines took us right to the Vatican City, the Colosseum, Spanish Steps, etc. It was nice to be able to come back to a quiet residential area once we were done sightseeing for the day!
The apartment was clean, spacious, and well stocked with essentials such as bath towels and blankets. There is no kitchen but there's a microwave and such if you want a quick breakfast or coffee.
Definitely check out La Nochetta around the corner - it won't disappoint! One of the best restaurants I've eaten during my time in Italy.
