Great Location, easy to find, very clean and airy apartment. We were met by Jose's delightful Mother who showed us around the Apartment and explained where everything was.
The station is just 5 mins away which enabled us to easily reach Lisbon, Belem and Cascais, easy walking distance to Estoril where you can pick up the bus to Sintra( get a daily ticket as this includes the shuttle bus around Sintra) really near to the Beach and the promenade which reaches all the way to Cascais if you are feeling energetic.
The road outside is busy but we were used to this by the second day and the bedroom is quiet with no road noise.
All in all a very enjoyable stay with no down side.
