I traveled with my dog and was in the apartment of Elisa for 3 weeks. My daughter was 5 days with me, and a friend 7 days. Elisa was always very nice and kind to me and she picked us up at the airport and offered to drive on the return. When something happened she came and repaired immediately. When I arrived it was 12 degrees and raining in Cascais. The apartment is located in 1 floor with marble on the floor. It was just a hot oven and it was turned off. Everything is relative and when I analyze my stay compare to what I'm used to. In Norway we never turn off the heat (only in sommer) because it takes time to warm the house when it is cool. For me the apartment was cold and wet. When the sun rose it became better. The apartment shares a gas heater with an apartment next door. When the neighbor uses hot water it makes a lot of noisy in the living room where the equipment is installed. There is a large plot around building that my dog had enjoyed. It is 5 min walk to downtown / old Cascais which is very good.
All in all, I think that the apartment is ok for shorter trips in summer.
