The apartment is great, it's ideal in both size and location. The room is comfortably big enough to happily accomodate 2 people and it's nicely finished. There are shutters on the windows so you can avoid being woken up by the early morning sunlight and the room was cool enough to not need air conditioning or a fan (July).

The beach and the main square in Cascais are only about 2 minutes walking distance, and the train station is 10 minutes away, where you can get a ~40 minute train to Lisbon for daytrips.

Maria and the apartment were great. Recommended.
