Sacha was a great host and my 1-week budget stay at his place was a great & affordable way to start my Porto journey. The bed would be the one real complaint I had, since it wasn't the most comfortable and it made creaking noises when I moved, but after walking around the city for hours I always slept well despite it. Also as others have noted, it can get cold & humid - but that didn't really bother me too much.
