Maria's place was a unique and cozy stay amidst a very well kept and nice garden. The annex catered to our needs, and it was easy to make day trips to Lisbon, Sintra and Ericeira from there, although it was a bit of a drive back from dinners in Cascais / Estoril as there weren't restaurants in the neighborhood. There's a dog training center next door, and whilst it didn't really bother us, the dogs did bark quite a bit (Maria's dog was very nice and well-behaved though).
Maria was away for the most of our stay, but her son was really helpful around the house.
