This studio apartment is in such a GREAT location! And yet it’s very quiet inside; you don’t hear any street noise. Charles is excellent in responding to any concerns. I had a special request for some extra linen and it was there that day! We appreciated the self check in with a lock box…no waiting around for anyone. We even got to check in a bit early. It’s a “budget” apartment but it was just fine for us. We also really enjoyed having the extra space of the terrace. We recommend Charles’ place for your base to explore Porto.
