Sintra is so nice to stay! Lissabon is easy to get to with public transfer. The location of the appartment is lovely, so near to lovely little restaurants. The minimarket for groceries isn’t always open. If you need groceries it’s a bit of a walk, especially coming back up the hill. If you have a car that should be a problem, also busses go quite often. instructions for arrival and usage are very clear and complete. It is a bit moldy and dusty, that is good to know for people with allergies.
