The apartment is in central location, very easy walk to get to all the attractions. It looks exactly as it does on the photos.
Maria was very easy to contact and always responded to any questions I asked. She happened to be away at the time of our stay, her friend Sabrina let us in and allowed us to check in early.
Overall I would recommend staying here but there are couple of things to be aware of: the apartment does not have any essentials (e.g. Shampoo, cotton buds).... It is situated right outside the basilica which means that bells ring everyday early morning for good few hours. I could not get any sleep in the morning which is a downside when you're on holiday and you're trying to have a lie in.
