The apartment from Alexandra is exactly as described! It was a perfect location around the wonderful Alfama neighborhood to explore the city. After a day of hectic sightseeing in Lissabon it felt nice and safe to return to the apartment.
It was super tidy and cozy and has everything you could need. It does take a few stairs to get to the apartment, so remember that. Asides from that we really liked the stay... our only complaint is that you can very easily hear the neighbours below. To the point where we could almost heard what they said. For me that felt a bit uneasy.
Asides from that, if you plan to explore Lissabon, this is a great central location to stay.
