My stay in Mário's place was perfect! I was traveling solo, and this studio was the perfect size for one with all the amenities and comforts I wanted. It's centrally located just a few blocks from Sao Bento station, so I was able to stop by between sightseeing around town. Mário's staff was available to let me check in early and gave great local restaurant recommendations. I would definitely stay with Mário on a future visit to Porto!
