Yes, yes and yes! I absolutely recommend this place as the location hands down is the best - no need to use any public transportation, everything you want to see and visit is in the walking distance.
Barbara is such a sweet lady! She gave us a handful of great tips but what's most important is how clean the apartment is! Big thumbs up! It's like your mom did the cleaning it and you are afraid to mess it up. :) Also, Barbara was very thoughtful to provide a little treat for us upon our arrival.
Porto is a lovely city with great scenery and tasty food, so looking forward to going back!
