This airbnb is the "Pena Palace" of Alfama or perhaps, the Ritz Carlton of Alfama! I highly recommend this place.
Location - So central that you can walk everywhere and is accessible to the tram and metro.
Airbnb - Superbly clean; excellent amenities equipped with washer, dyer, iron - name it, you'll find it! So stylish. Apartment smelled fresh (courtesy of Ritual).
Security - Everything was a passcode-protected and we felt extremely safe.
Hosts - Amazingly responsive and very accommodating! You can always count on them.
We're so glad we stayed an extra night (total of four nights).
We will definitely go back to this place. In fact, I have already recommended this airbnb to my friends.
