Great apartment - we chose it because of its location not too far from the train station but you can also walk to main attractions like Spanish stairs and the colosseum so it's still pretty central.
What I liked about the apartment was that it had two large bedrooms so plenty of space for spreading out the suitcases! Nice modern kitchen. Also two bathrooms though one had the door handle hanging off which I'm sure Marco will repair. It also has a lift which was important for my parents.
Marco is a good host, very quick to reply to messages before you get there. He met us at the apartment so that was easy.
