Very nice apartment, nicely decorated, everything very new and everything working properly.
The neighborhood is perfect if you want to be in a quiet place, but with all the services around, and the fantastic coastline. Oeiras-Carcavelos is an area really nice, with a lot of places to visit (the beach is great, but also there is several parks really nice). It's also easy to take the train to go to Lisbon/Cascais.
We really enjoyed it!
