I've never written a bad review on Airbnb but I strongly recommend avoiding this place because of the faulty electrical wiring.
Within 1 hr of arriving at the property, the electricity went out completely and we had to troubleshoot the fusebox. The apt does not have central heating so they provided space heaters in each of the 5 bedrooms. It was about 45 degrees during our visit so it was pretty cold inside and we needed to use the heaters. We could only use the heaters on low power otherwise the power would go out. During our stay, the power went out 9x over the course of 3 days. One time, only one of us was home and was in the shower when the power went out. One morning the power kept going out so I couldn't WFH.
The power went out randomly, it wasn't usually in response to something being plugged in. I think all Airbnb stays should at least have reliable electricity. There are plenty of lovely places to stay in Lisbon, don't take a risk on this apartment - it's not worth it.
