This accommodation is spacious, well equipped, with its own south facing terrace and swimming pool. It is located in a very safe, peaceful, residential area, with a local supermarket and restaurants within a 5 minute walk.
The host even arranged for us to be picked up at the airport, and provided us with our own personal chauffeur when we wanted a day at Sintra.
The flat is close to Sao Pedro station which is on the main Lisbon - Cascais railway line, so the location is excellent to explore the local area and for generally getting about. Just over the railway line is a smallish but perfectly good sandy beach.
If you are wondering whether to book this place, let me reassure you, you won't be disappointed.
