We had a great stay at Rita's apartment. The apartment is right across from the path up to the Moorish castle and a short walk into Sao Martinho. It is a bit of a walk up (I mean...UP) from the train station, so if you have a lot of bags, you may want to take a taxi (there are many waiting right outside the train station). The back patio is lovely with a glass of wine after a long day of palace visiting. The kitchen was nice with everything you need. I definitely wanted to stay longer! One warning - there isn't really a grocery store/market of any real kind within walking distance (we ended up walking down to the Pingo Doce in Sintra), so you may want to plan ahead on that front.
