My friend and I loved our stay at Antonio's! It was extremely close to the train station and metro, which was very convenient. The apartment is beautiful, modern, very clean, one of the nicest I've stayed in. The surrounding neighborhood is not the cleanest, but with the proximity to the metro and train station, walking through one smelly street was nothing.
Antonio has a great set up with the cafe across the street, so we were so grateful to get a croissant and coffee each morning during our stay. Antonio is also fantastic with communication and always made sure our stay was comfortable. The apartment has two bedrooms, so be aware that another couple might also be sharing the bathroom and kitchen with you at the same time, but this wasn't a problem for me and my friend as we were leaving soon after the other folks arrived.
Overall, this was one of my best stays in an Airbnb and I highly recommend it.
