First time in Lisbon. We originally wanted to stay in center of town, but really glad we stayed in Parque das Nacoes. Its a quieter business district but with lots to do. Walking distance to transport (there's a bus and train hub at Oriente), groceries, mall, waterfront, aquarium, and running. If you're expecting to roll out of bed and be on a pub stool, then this is probably not the area for you.
The apartment itself was great. Its a higher level so with windows open on both sides, the place quickly cools down with a nice breeze. Clean and well furnished. We were able to cook many meals in the kitchen with the cookware supplied.
Ricardo was fantastic with communications and was super professional. Would stay here when I visit Lisbon again!
