The apartment is stunning! That's all I can say about the place.
I'd definitely recommend and would stay again at the Piano House.
We enjoyed every detail of it, from a quiet location, to the piano house.
We did have a problem upon check in, the room was not ready for us, however Rui and Bela quickly took care of it and made us comfortable.
Metro is near by, and made it easy for us to enjoy a day at Cascais, super recommend.
I am sure whoever rents this place will enjoy it fully so, just take a chance, and go for it.
