Met with our host, Vanessa, upon arrival. Although we were early, she still allowed us to store our luggage so we could enjoy the beach until check-in. The place is centrally located, two minutes walk from beach, shops, restaurants, etc. If you need to go somewhere, an Uber is never more than 3 minutes away.
The host - Vanessa - is a delight and was very helpful; for example when we needed an ironing board and she brought one over right away.
Will definitely recommend this place for a trip to Cascais.
