Gisela is an excellent Airbnb-host! All communication in advance was answered quickly, and she even stayed up to welcome us at our arrival after midnight! (We travelled with a 1 year old so the comments reflects this) The apartment is as the pictures shows; cosy and spacious, and without horrible carpet floors :) Gisela gave useful tips and answered all questions. She also got us a baby bed.
There are two elevators taking you quickly to the 9th floor. The view is towards town and not the sea, but this is not a big thing as you will more likely visit the sea every day instead :) There is a bath tub, a washing machine, TV, good wifi, and a large fridge. The bed room is towards the inner yard and sheltered from the noice from the street. There was construction work going on at the opposite side of the street but this did not bother us - we all three had a nap in the middle of the day.
The apartment is nicely situated really close to the metro line and the bus (which goes by the coast all the way to downtown Porto!), and there is a huge Lidl just on the opposite side of the roundabout. Would also recommend buying bread and fruit at the shops located in the same street. There are also great fishing restaurants in the parallel street towards the sea. You will smell the grilled fish in the evenings ;) The best is the short stroll to the beach - perfect! And you also have a nice cafe just where you arrive to the beach for beers and ice cream! Also with a little play ground for the kids. Swimming was great (water temperature like in Scandinavia = fresh), and the beach is so big that you always find a spot. The beach is great for families!
We recommend strolling along the beach towards Porto: There is a nice beach walk built up all along the coast - easy with stroller! Also some nice beach spots along the way. There is also nice 2nd hand shops just in the street where the metro station is. It was easy taking the metro to the airport too.
Matosinhos is a great place for families and people are really super friendly to kids! Every where there are kid chairs in the restaurants and people (even elderly!) stand up at the bus offering their seat. It is much calmer than Porto and less touristy. We had a great week and Gisela's apartment was perfect for our stay!
