Great location, a short walking distance from the beach in Estoril. Comfortable apartment with parking which was important for us. Host was available when we had questions or needed help.
Being Portuguese I did know the area very well and it is great even at this time of the year to follow the sea promenade along the beaches from Estoril until Cascais where you can find a bigger offer of restaurants, entertainment and cultural activities. The train to Lisbon is also a few minutes away and takes about 30 minutes.
I really recommend this location and would definitely come back.
