The appartment is in a great location, quite resort ,more spacious than expected ,relaxing ,modern and very comfortable. The balcony was an added bonus.A great base for our holiday. There's a well stocked supermarket with a butchers and fresh fish section just 5 mins away. The sea is under 10 mins away with beautiful cliff top views with a choice of good restaurants and bars. There's a beach on the costal walk just outside Cascais (a beautiful walk that passes Boca do Inferno, great for lunch and icecream) that's quiter without waves in an idyllic historical setting. Bike hire is cheap ( €6 /day) and easy as you start the coastal walk ( 10 mins from the apartment) and is definitely the best way to Guincho beach ,just under 4 miles with designated cycle paths parallel to the main road,spectacular views on the edge of the National Park. Apparenly there's also a bus and there are plenty of car parking spaces.The beaches there are golden ,Atlantic waves and surfing if inclined - all highly recommended.
Quickest and cheapest way to the centre of Cascais for trains to Belem and Lisbon and the bus terminal is with a prebooked taxi,takes 4-5 mins.
The 403 bus from the bus terminal is a beautiful, scenic ,historical route that includes Cabo da Roca on the way to Sintra ,it takes an hr and is well worth it. The 417 is about 40 mins to Sintra minus the spectacular views. Not a place to drive to as parking is non existent and appeared to be a problem.
