Fantastic apartment in the heart of Alfama, with a very warm welcome by João who gave us some great recommendations, including for vegetarian food.
Only note of caution: the organisers use a separate non airbnb system for check in. We were a last minute booking and the form autocompleted to the standard 4PM check in time, when we'd specified we were arriving at 9 on airbnb. Thankfully the team sorted it in time for our arrival.
