The apartment is located in a very quiet place but you've got the closer train statation less than 10 minutes walking so you can arrive to the city centre of Lisbon easily. The city centre of Cascais and Estoril are close as well if you want to dinner/lunch there. In adittion, you can park your car in the same street.
The apartment was very luminous, small but functional and has all the facilities you can need to enjoy your trip, including vodafone TV.
Anterro, the Sebastian's friend who welcomed us, was very friendly and knew how to answer to all our questions.
Obviously, I recommend it :)
