We stayed here for 6 nights. we loved place. it had everything you needed, even dishwasher tablets and liquid. the place is spacious. the bed is very comfy.
the location is also great. you can walk to all Sintra attractions by foot. and the bus to Cascais is just 5 min walk away.
there are a few small grocery shops nearby as well as quite a lot of restaurants. our favourite was Mela Canela.
Sofia was very accommodating, we could check in earlier than 16.00.
there was a bit of humidity but it didnt disturb us. there is also arco/heating, also convenient
we definitely recommend this place!
