Hello!
The main point I guess one is choosing this house -- it is its location. You will hear the roar of waves and feel the power of the ocean (but don't worry it is a safe shelter).
There are two fine restaurants just near the house. They are pretty busy even at the low season, so mind to reserve you place.
We rent the car so it was easy for us to reach everywhere, however I noticed public buses run constantly.
Costa Family representatives are extremely supportive, they won't leave any your question unreplied.
Enjoy the beaches and the view points! Formally, Caba de Roca is the most western point (and it is 20 mins by car) but actually you will feel the same just at your place.
