One of the closest apartment to colosseum which is just opposite side of colosseum.
Lot of nearby places to eat and drink as well which are top rated on trip advisor.
Make sure to try the restaurant suggested by William.
Also, train station is just 5 mins walk from the apartment and it’s convenient to visit a lot of places quickly. Plus if you prefer to stay late at night in town then Über just takes 15 Euros to drop you back to this apartment.
Definitely worth trying.
