We enjoyed our stay at Ana and José's guesthouse. As everyone mentioned, Fred — the friendly dog — is the star of the show. Without fail, he slept in front of the door and begged for belly rubs — the best!
The house has everything you'll need and is well located to visit Lisbon, Sintra, Ericeira, Mafra, etc.
Although the guesthouse is on the same property as Ana and José's house, there's a feeling of privacy — even when in the swimming pool that faces their house.
