We can definitely recommend staying at Goncalo and Ines´ apartment. There is a lot of space, we were able to use the living room, TV and kitchen and had our own bathroom which is great. Goncalo and Ines were very friendly, we could ask them for any recommendations and they respected our privacy. There are a lot of supermarkets close by and you can walk to the city center in about 20 minutes, although the metro to the airport and to the city center (with connecting trains to Sintra and Cascais) is also very close by, if you prefer using those. Overall a very good experience that we can recommend :)
