Mario's place was perfect for my short stay in Porto. The apartment was super central, few minutes walk to all major places. The apartment has multiple rooms, with other guests, but they were all very quiet and considerate. The apartment is clean and well equipped, with comfortable furniture. You can also download and use Mario's travel guide app, which was quite helpful! Overall the experience was great, but if you're looking to have interaction with the local person, this may not be the place for you. Otherwise, I highly recommend this central and convenient place!
