As everyone said before, this studio has the best location in Lisbon. It's perfect to explore Alfama and be there early in the morning and it's convenient to go to most of the other Lisbon famous sights seeings. Another thing that I liked was a very comphy bed - I slept very well there with my baby. I loved wooden beems - they give i nice look to the place and they're handy to put things on. I liked that in the morning you've got plenty of sunshine in the room and also that despite a very touristy location the place is very quiet. I had a pleasant surprise to discover my favorite Lisbon mural painting right in front of the window - this was wow!
Now, couple of small things that I liked less. The bathroom had a bit of this unpleasant smell. But I think it's quite common for old buildings in Alfama. Other thing - host is quite procedural with filling in link with info about passeports and flight number. I understand that it's good to follow rules, but it adds on work before departure.
