This is a very cute little flat, very conveniently located in Sintra, but away from the busy center. It's an easy walk to the train station, and over to the "heart" of town near the palace.
Pros: cute, clean, comfortable (really comfy bed), well appointed (soap, shampoo, and a hair dryer! hallelujah! in addition to some kitchen basics, and a tv with plenty of channels)
Cons: a bit noisy (capoeira went on in the hall on the corner, all afternoon until midnight, and cars and people coming home late at night do provide some noisy distractions - especially if you are sleeping with the windows open for fresh air), I had some issues with sewer gas in the bathroom which made for a very stinky stay, and I do think they could have handled my concerns a little better
Overall - it's a great little spot to use a base for exploring Sintra, especially if you are lugging bags to/from the train station. Just maybe bring some ear plugs. And a scented candle.
