The best part of Luis’s place is the location. It’s a 5 minute walk to the river and shops down there, super close to interesting little winding sidestreets with nice shops and hole-in-the-wall restaurants, and a 20 minute walk from the super touristy areas with heavy foot traffic and generic cafe and shopping experiences. Also there’s a Starbucks next door if you need a quick caffeine fix but don’t want to wait an hour lounging at a cafe.
Pro tip: rent scooters and cruise up the Douro River in the Douro Valley. Incredible.
