Maria’s apartment was wonderful. I only stayed for one night as I was in my way to Douro but check-in was east, the location is central and near the train stop, and the apartment was clean and as described on the listing. There’s some construction going on in that part of Porto and they start early but it’s nothing that can’t be blocked out with ear plugs if you’re a sensitive sleeper. You will probably hear it no matter where you stay!
