An excellent host - just WhatsApp Cosimo and he’ll reply within minutes. This apartment is pretty small, but the location makes up for it. It is roughly 30 minutes walk to the Colloseum, or just two stops on the metro (the nearest is Piramide). The train (from Ostiense) to the Vatican was €1 and took about 20 minutes. The stairs are steep and narrow, so I wouldn’t recommend if you have mobility issues. For the location, and amenities, this place is really great value. Also, Flavio al Velavevodetto is an amazing restaurant just around the corner (mains from 10€).
