We spent a month at Ana's place. The location in the Alfama can't be beat and it was super easy to check in and communicate. The apartment is bright and well decorated. We did have difficulty having two people on video calls at the same time and the internet signal didn't always reach into the bedrooms. You'll need to bring/buy basics like soap, salt, olive oil, and napkins but there is a Pingo Doce 10 minutes away. The back bedroom could get a musty smell but that might have just been because it is tough to ventilate it (it's next to a bathroom with a great shower). This being said, we would stay there again if we were looking for a place in the Alfama.
