This is an excellent apartment/flat for small families or two couples. This place is much larger then the photos make it look. Each bedroom has a queen sized bed and there is room for a Pack N Play/Camping bed for a small child in either bedroom. The master bedroom has it's own full bathroom.
The view from the 4th floor is stunning at Sunset and it is a quiet neighborhood at night. Parking is free out front or Isabel has 1 free parking spot in the underground parking area.
There is a grocery store on the street level of the apartment building or you can walk/drive to the Jumbo which is not far away.
The beach is a little far to walk to, but it can be done or a 5 minute drive will get you there. Parking is free on either side of the main beach road. This is where you will find restaurants, bars, many kilometers of bike/walking path, and for those with children there are play areas designed for them.
The best part of this place is that it is only a 12 minute drive to parking areas where you can walk onto a bridge that will take you into the center of Porto. We did not use the local bus, but there is a bus stop very close to the apartment. It may require you to transfer to another bus or the Metro line in order to get into Porto's center.
I highly recommend this apartment, especially if you want to stay near the center of Porto, but have a more peaceful neighborhood experience.
