During our 6-weeks in Lisbon, the Metro Rossio (Linha Azul--Blue Line) was pretty much our go-to…read morefor public transportation, it being a mere 5-minute walk downhill from our apartment. For the most part, the station has been perfect for our various in-town excursions. Perhaps a bit for attention to cleanliness would do it some good. Lately, there's been water puddling-up at one of the entrances along Av. Liberdade, with no caution signage, which could easily lead to slips/falls. Thus, I'm taking my review down a notch. Otherwise, all is good at Metro Rossio.
