Very comfortable accommodation, has all the necessary amenities. The host was very kind and provided us with a lot of information about the area. Two train stations are nearby for easy access to both coastal places (from Alcântara-mar) as well as more inland places and Sintra (from Alcântara-terra).
We did get ants, so I would advise not to leave food out in the open, and we had a miscommunication with check-in which meant we had to wait a while but otherwise it was a great place to stay.
