Great location to explore Rome (by foot). We walked to the Pantheon, Vatican, Colosseum (30 min), Travestere. Villa Borghese is a bit further away, but on walking distance if you like to walk. The possibility to park our car just in front of the apartment was perfect.
There is some noise from the restaurant downstairs, but that makes sense for a location in the centre. Only thing to note is that the bed is not that good.
