Carolina's place is in a wonderful area of Porto. Check-in was easy. It's convenient to almost anywhere you'd want to be in the city, including the banks of the Douro. Distances were surprisingly short and we walked everywhere. The apartment is extremely clean and comfortable. Carolina was responsive to our questions and gave us excellent suggestions, which we followed up on, like the excellent restaurant O Buraco, a few blocks away. We would happily stay here again.
