We stayed for two nights and loved it! The check in was easy, the place is exactly as it looks, and on the ground floor which was nice and cool. Also, the Alfama neighborhood is a fun area and you can easily walk to the other neighborhoods, like Bario Alto. Would stay there again for sure.
Only warning, on Saturdays in June there are celebrations in Alfama that go well into the night (2am). It didn't bother us as it was fun to participate, but it's something to take into account if you stay in June.
