I stayed at Casa Antiga for one night and met several women who worked there - everyone was incredibly kind and accommodating. I was able to do a slightly earlier check in, given a tour of the grounds and a glass of Porto, and able to leave my luggage for a few hours after my check-out time.
My room was clean, beautiful, and had everything I needed. Location is walkable to parks, shops, food, tourist areas. I would definitely stay again.
