It's a nice apartment really near to the colliseum, you can park in the street for free if you find a spot, the metro station that conects you to any point of interest, ist just few steps away.
the apartment is really nice, the instructions for the check in were really clear and easy to follow.
There's a restaurant just next to the apartment were you can have a nice breakfast, meal or dinner and the prices are really accesible.
I just suggest you to bring a rag so you can dry the dishes, everything else was great.
