We enjoyed our stay at Maria's apartment. It was very cute and comfy. The balcony was lovely and we enjoyed spending our evenings out there. The apartment directly across is abandoned so you won't have any neighbors looking directly at you. We were awakened every morning to the loud screeching of the seagulls, but we got used to it towards the end. I think that would happen anywhere in Porto. Our trip to Porto was amazing and magical and the apartment was comfy to come to after a long day of exploring.
