We really enjoyed our stay in Lisbon. The neighborhood is rustic and you feel almost like a local. You can walk down to the city center for the energy, plazas, and waterfront area. Take the nearby street cars and enjoy the thrill of sharp turns and narrow passages as you explore neighborhood by neighborhood, hill by hill.
There are local restaurants within fifty meters or less and we ate locally everyday because the food was market fresh fish, veggies, meats, and often grilled with olive oil, etc., you get the picture? Oh, we ate very well for around 22-27 Euros for dinner or lunch for two in the neighborhood, and that included drinks.
Go to Lisbon, its a remarkable part of the world with kind people, great food, charming neighborhoods, beautiful scenery, and there is something for everyone.
