We had a wonderful stay in Porto at Miguel's place. We arrived an hour before check in and were allowed leave our luggage while the appt was finished being cleaned. Manuel directed us to some local food spots and we had a pleasant wait at the park nearby (they have lots of modules and even a zipline- lots of things to explore for our 8 and 11 year old).
The appartment was clean and we appreciated having 2 bedrooms. The AC is a wall unit in the entrance so on the hot nights, you'll want to sleep with the bedroom doors open. Extra pillows and towels would make the stay more comfortable but isn't that big of a deal.
The location was fantastic as it was just a 10 min Uber ride to city center and all historical sites.
Manuel is prompt in his communication and is very generous. We would recommend staying at his place to our friends and family visiting Porto.
