We (couple, early 30s) stayed at Carla and Joel's home in Alfama in Sep '22 and were greeted with a bottle of sparkling rose. The apartment is nestled in the center of Alfama which was great because near to restaurants, tourist locations, etc. It also means lots of stairs to get to the location but this was really only an issue when arriving to the bnb with luggage. Also, because the door opens to the street, privacy was limited unless you stayed in the bedroom. The only other issue that we had was that it was a little tight to navigate around the bed in the bedroom due to lack of space. We didn't try cooking (because there were so many cheap delicious restaurants nearby) or watching TV (because there was plenty to do). Overall, a great experience and would highly recommend if stairs aren't an issue for you.
