This is a charming apartment on the 2nd floor (3rd floor North American). The apartment is large with four sets of windows facing west. During the day, the apartment was bright, but the low level lighting made it quite dark at night and difficult to read. I liked having separate dining room. The hot water is on a tankless heater which required a few minutes to heat up. The tub would benefit from having an anti-slip mat. We did not cook in the kitchen, only made coffee.
The neighbourhood is on the mountain below the castle a few metres from the Cathedral and the streets are very steep. Nearby are a number of nice restaurants, pastelaria and a grocery store. We walked most places. The metro is about a 10 minute walk. The agency had warned us of noise but there was little from the outside. However, we could hear every movement and noise from the apartment above us.
We had good communication with the owners. One issue is that the webpage for Portas do Teatro shows pictures from a number of apartments and it is not easy to see which pictures go with which apartment. I would suggest the pictures be re-arranged by apartment.
We enjoyed our stay here at the apartment. Other than not wanting to experience again the challenge of managing the hills (we are two seniors in our 70s), I would not hesitate to stay here again.
