Finally got a flat in Cascais. Cascais is situated 30 minutes from Lisbon by train on the Atlantic coast. It is a really nice little town and I would recommend it as good destination for a weekend holiday in the summer. So basically I am going from this:
Anjos, Lisbon (centrally located but really run down)
Cascais, Cascais (sweet town by the beach)
To be honest, Lisbon is great too. I went to see the big "Rio-like" Jesus but was more impressed by the bridge next to it looking like Golden Gate bridge. Maybe it doesn't quite replace actually going to San Francisco, though..
