For the budget minded, Lisbon is king. Here you can watch your pennies and do it in style, starting with staying at one of many design-focused hostels. And this week, starting today, you can gain entry to a score of venues that are usually either reserved for VIPs or are otherwise unavailable to the general public. Today starts Lisbon Week, an cultural open doors event, that allows you to enjoy history tours of rooms that are normally off limits. A biologist will lead you along the city's newest section of a peaceful greenway. And an art tour will highlight paintings, video installations and sculptures in unusual venues. You'll even be able to step into several embassies that will showcase their relationship with Portugal.
