This full size apartment is great. Fully equipped kitchen and full sized bathroom. A grocery store and several cafes are right out side the apartment's front door. You can walk to downtown Porto or ride the metro which is also right out front. Three of Porto's train stations are a short taxi ride away.
Your hosts are quick to respond to any questions you may have and meet you in person to exchange keys.
We would definitely stay here again and highly recommend this apartment to anyone considering a stay in Porto.
