This place is great. It's charming and cozy, with warm lighting and a nice large terrace that offers a lovely view of Sao Vicente. I loved the exposed beams, stone, and old tilework. The bed is on the firmer side, which I liked, and the couch is comfortable too. The bathroom is a bit of a tight squeeze (as are most in Portugal, it seems), but the water pressure is fantastic and it gets nice and hot quickly. Location-wise, it's right there in the Alfama, with easy walking access to all that it has to offer. It's right around the corner from the sprawling Saturday flea market Feira da Ladra which is a must-see.
I do have to mention the bizarre stairs. I've never seen stairs quite like this. They are somewhat difficult to navigate, but we got used to them quickly. That said, it takes focus to descend, especially at night.
Lastly, I want to commend the host for their speedy and satisfactory response to an issue that arose that was beyond their control. I definitely recommend this space.
