we had a great stay in Ericeira.
the appartment is really beautiful, enough space for our family and Sergio did a tremendous job as a host!
The location is incredible: you are in the middle of the old village, a few minutes away from the fishermen"s beach, close to all necessary shops and the ride from Lisbon's airport was very straight.
one note though as it is not obvious in the description, you have 2 bars directly at the corner of the appartment with music playing til late in the night. even with the windows closed, you still hear the bass and if you have problem of sleep, you'd better think about another area of the city. For us, it was no problem at all!
