A really bad Airbnb experience.
1. Alfama is close to center but a non-cental area. Its a minimum 20-min walk from the central Plaza.
2. Alfama is the dirtiest area in Lisbon.
3. Alfama didn't feel safe after midnight.
4. The building was old with a terribly steep stair, making it difficult even to carry your luggage at the first floor.
5. A non-soundproof apartment. Too many annoying noises during the night.
(it also seemed strange to us that there was a requirement to take the trash out by your own at check out)
However, we should mention that our host was very communicative and willing to help. In addition, Alfama is great for listening to Fado music.
