We were lucky to unknowingly stay at Mario's place as his first guests. His apartment is newly renovated, with airconditioning (very important for these Seattlites from a mild climate) and multiple ceiling fans in the space. The bed was very comfortable and Mario provided drinking water, some treats, and espresso! The wifi worked perfectly. There was free street parking out front, too!
Mario was very gracious and gave us some tips for visiting the city. He is very close to the city center, near the cathedral, and an easy walk to many popular places.
I would highly recommend staying here if you are looking for a comfortable, easily accessible (ground floor apartment with only a couple steps into the space), central apartment with a kind & responsive host.
