We had a great stay in Porto at Joaos apartment. The beds were extremely comfortable. Everything was spotlessly clean. The location although in the centre of the action is quiet at night. In other words it is a perfect location.
There are great restaurants and bars just outside the front door. There is a great bakery straight opposite.
If I was returning to Porto I would definitely seek to book this apartment again. I highly recommend this apartment to any single or couple for their visit to Porto.
