Clean, comfortable and quiet (although this was probably due to the lack of tourists this year, as there are a few bars and restaurants in the area). Great location in downtown Porto and reasonably priced for what you get.
Only a couple of complaints: Housekeeping did not come at all on one day, and on another day, threw away my dirty clothes that I had put in a plastic bag on the floor, thinking it was trash.
However overall, a good stay.
