Carlos's place is wonderfully situated near the Santa Apolonia train station without being seedy. Sparklingly clean. Vibrant street scene but quiet due to high quality windows/doors at the apartment. It's a short walk to the Praca do Commercio. We had a great time walking all over the city. If you go, be sure to eat at a restaurant Carlos recommended - Maca Verde (Green Apple). All dishes were great, and cheap. Oh my. Hope to return soon..
