As others have said this is a great little property. It is perfectly placed for all the sights and facilities of Cascais - beaches, restaurants, bars, shops, rail station & bus station. By that I mean easily walkable in 5-15 mins. Cascais is a great base for all the Lisbon sights (40 mins and €5 pp return) and Sintra history.
The 'casa' itself is spotlessly clean and well stocked with a necessities. I personally enjoyed the size of the shower stall the plentiful hot water and the pod coffee machine. My beloved loved the pool, the comfortable bed, teapot and teabags. The 'welcome pack' was very thoughtful and much appreciated as was Teresa & Miguel's help with local knowledge.
We are a semi-retired couple with 2 adult children who like to spend some time together in the sun. We chose Cascais as we felt there would be enough of interest in the town, but also with easy access to Lisbon.
The town is very picturesque with plenty of places to eat and drink at reasonable prices.
The apartment is extremely comfortable with everything you need. Room enough for 6 or even 8 at a push. We were welcomed by Fernando and Maria who were very helpful.
The only criticism is that the property is nothing like 300 metres from the sea. It is more like 800 metres from the town and a further 200 or 300 from any of the beaches. That said, we will more than likely return.
