Lovely house, lagoon area has breeze even at height of summer in August.
Good base, Obidos, 20 mins away, is a medieval town with very impressive castle. Beautiful buildings with local artists selling paintings and prints, plenty of good restaurants. Lisbon is an hour away.
A car is essential to get around, as the house is situated up a forested hill above lagoon. Excellent walks and runs around the lagoon, which is only 15 mins away by foot. Lots of activities available, we opted for kayaks which were very good value - €15 for an hour for a double or €10 for a single. Really comfortable and proper seats even for us middle aged with back issues.
This is a beautiful, quiet area, with lots of interesting nature including flamingoes in August.
There are any number of fantastic beaches within 15 mins to 30 mins away, Praia del Rey being the closest.
