Location of Oceanario is excellent - it's right on the waterfront, walking distance to lively historic downtown, beautiful park and public transportation if you need it . The apartment is spacious, very nicely decorated and very cozy. The plot is big and very well kept. The pool is definately one of the best we've ever used. Very few people use it, so it feels like a private pool. Cascais is a great place if you want to travel around (Lisbon, Sintra, Fatima etc. are all within a short train or car ride) or just enjoy beaches famous for windsurfing.
