There couldn't possibly be a better location in Porto! The views of Ponte Luis and the Douro were spectacular. We only had 1.5 days in town but because of the location were able to see it all. The 4th floor walk up didn't bother us either. It was little smoky in the apartment but two of the bedrooms had windows overlooking the river so we got a breeze to circulate the air. The apartment is enormous and charming and overall clean although there was a bit of mold in the tub (which could be easily cleaned). We didn't get to meet Miguel personally as he was out of town, but he was super accommodating and made sure we got the keys upon arrival. He also had great recommendations in Porto. Overall it was a great time!
