Alessandra's flat is in the heart of Alfama. It was so great being in the middle of the festival that was taking place while I was there. Everyone in the hood was friendly, accommodating, and helpful. I was travelling alone and walked through the streets at night and I didn't feel worried or concerned about my safety.
The flat itself is perfect for one person or a couple. Just to note that the steps going up to the flat (whether you're on the 1st, 2nd, or 3rd floors) are very steep so the building may not be the best fit for those with mobility issues. The space is clean and bright; however, there is no view.
I would recommend her space to my friends thinking of visiting Lisboa!
