I stayed for several nights as a solo traveler. All the reviews are accurate -- it's a cute little studio right in the center of Porto. Can be a bit loud at night as others have said, as Sao Bento roads are the main hub and ambulances and buses go through -- didn't bother me much, but was noticeable. Great stay for one, might get a little cramped for a couple after more than a few days, but the ability to walk anywhere around Porto in 15-20 minutes made it a great base for exploration. Lots of great restaurants and transport at the doorstep. There was no washer/dryer in the unit, but I never asked about it, and Elsa and Rubina were very responsive and came to say hello the first night, so I imagine there was one in the building if I'd inquired about it.
