Thank you for a memorable stay. The apartment is not the newest but it works well for what you need and the location is phenomenal. I would stay here again.
If you take the Metro from the airport (which I recommend) you should get off at the "Baixa-Chaido" stop and most importantly leave via the "Rue du Largo" then "Rue du Garrett" signs so that you will be going downhill with your luggage 🧳 instead of uphill. 😉 Lisbon has some steep, slippery, walkable hills and the apartment is along one of them.
