Very good location! Just in front of the roman forum. 10 minuts walking to the nearest Metro station (circo Massimo), 15 minutes to the Coliseum. Quite place. Charming appartement. You can reach pretty much every monument just walking.
If you want to hang out on nights you might have to go to others areas in the city, but if you mainly go to visit, this appartement is a great choice. I recommend it!
