We enjoyed our stay at Seaview Elegance. The top-floor location is excellent and we really enjoyed the beautiful views. It did not bother us to have to navigate one flight of stairs. The location of the apartment worked well for us. There is a decent grocery store about 1/2 mile away, and some smaller ones even closer. The walk to the beach using the tunnel by the train station works well. We found that Uber is very reliable in the area -- a ride to Sintra was about €12, and airport transfer around €25. Our time was limited, but we enjoyed sitting on the deck and watching the sky at sunrise and sunset. The showers required using a hand-held wand, which we weren't really used to but figured out. Water pressure was good. The blind in the bedroom doesn't go quite to the bottom of the window, so bring a sleep mask if that matters to you. It was quiet and we were able to sleep well. Sarah & Pedro were quick to respond to inquiries and provided us with some helpful area information. Cascais is a fun and vibrant area, with so many sights to see. We wish we had been able to stay longer!
