Mars' loft is very nice and comfortable. I made a new reservation immediately to go back there as soon as possible!
The architecture and decoration are lovely, with many artworks; the furniture and equipment are very comfortable; and the Cascais quartier is quiet, attractive, modern, very centric and calm.
The breakfast in the shared zone was very good, and there are many interesting books to read or browse.
If you plan to go there, have in mind that the loft is situated at the top of the nice wooden stairs, and you have to climb the two floors.
