Such a cute place to stay in the centre of beautiful Alfama district! Most of attractions in Lisbon is walking distance. However, the ceiling was quite low for me (6ft), which I had to bend down my back or neck just in the bedroom, rest was fine. And the bathroom could be little smelly since the building is an old apartment, there is no fan ventilation and have only one window and one small door to outdoor terrace in this apartment (the cutest part though). And little noise from upstairs and from staircase of the building.
Overall, if you are not really sensitive with such thing, it has great location and good amenities to stay! And the bed is really nice, had good sleeps.
