Any longer than a few days, and this stay will be problematic for you: 1. A/C trips the breaker. 2. Activating anything more than one stove ring (burner) at a time trips the breaker. 3. Two window ledges are rotten, one is rotted off its hinge. 4. The A/C unit leaks water through a moldy (tape-sealed) cabinet onto the kitchen counter and floor. 5. There are very few stove-worthy pots and pans and very few utensils. 6. Nobody by the name of Pedro answers when you call, or answers Airbnb interventions. 7. A hole above the stove drops fuzzy gunk onto the stovetop periodically. 8. Repeated requests for cleaning will go unheeded.
In addition, it should be noted that while this location is very central to Alfama's fado club scene, it is noisy well into the morning hours, even on weekdays. If 4 flights of steps isn't your thing, do consider the climb.
