Very convenient and clean and great location in a calm/residential area. 5 mins walk to the nice São Pedro beach; some 10 restaurants within 10 mins walking distance; 2 places for breakfast under 2 mins walking distance; Train station in less than 1 min walking (takes 20/30 mins to Lisbon; 10/15 mins to Cascais). You can hear the trains passing from the apartment but we didn't find it problematic.
