We didn't get to meet Joao, but he was responsive to questions and messages. A colleague of his met us at the apartment the first night to give us the keys and show us around. The apartment itself is neat, tidy, and efficient. It is on the 3rd floor up a steep flight of stairs, and the bedroom is up another steeper flight, so people with limited mobility may have trouble. Open windows provide a nice breeze, and the views from the kitchen and terrace out over the river are great. We didn't use the kitchen so I can't comment on it, but the bathroom was modern and spacious. The apartment is inside the castle walls, so the area can get very crowded during the day, but is pretty quiet at night and in the morning before the castle opens. Use the nearby Elevator Castelo to avoid stairs on the way up to the castle. FYI, if you plan on using Uber, only residents, taxis, and public transport can access the area by car (as we learned after the first night), so plan on a 5-10 minute walk uphill from the areas where Uber drops off.
