This Airbnb is wonderfully and perfectly located in the center of Alfama. My partner and I reached everything by foot. Alfama is very hilly so be prepared to go up and down many stairs to get around there. The neighborhood is very lively. We got to enjoy Fado from one of the restaurants close-by in the evenings, this was very lovely. A big downside that is important to know (which we were not aware of from other reviews) is that at night there is lots of noise because of the waste containers right next to the apt. We stayed there a week and were woken up every night by the trash man rolling the containers around at 1 and 4am. We had to close the windows every night and even with them closed, we heard the noise. There is air conditioning available, so this could help against the heat.
Other than that, you pretty much get what you see in the pictures. The apt. is small but has everything you need. If you stay for more than a couple of days, be prepared to buy soap and toilet paper. I hope the owners fix the couple of things that were broken. After an email to them about this, they responded quickly and suggested someone come by for the repair. Our last day we had to carry our bags around because the owners did not respond to my email if we could leave our bags until our flight in the evening. Overall, it was okay but we did leave a little disappointed because it could have run smoother. I probably won't be coming back or suggesting the place to a friend.
