Mario's place is a great duplex situated at the edge of Bairro Alto and Chiado! It was conveniently located close to the subway station and other sites. The place was in the heart of the nightlife as well but was surprisingly quiet thanks to some heavy duty windows and panes. Mario's office is actually on the first floor of the building so he is conveniently available during the daytime if there are any issues. Overall, would highly recommend a stay here!
