We had an absolutely phenomenal time at Sérgio's apartment! Sérgio was a gracious host and ensured that we had everything we needed for our month stay. His communication was perfect and everything was done with a smile :). The apartment itself was extremely clean, and is conveniently located right next to the bus stop that runs all around Porto, less than 10 minutes to downtown. Grocery stores all around: a minimart across the street, a lidl supermarket only a 5 minute walk away, and a large continente 10 minutes away by walk. If we return to Porto, we'll be staying here again!
