The room itself is great; modern and cozy, plenty of space for 2, bad thing is noise from post office outside starting at 4:30am.
BUT, be mindful of the neighborhood because 3 of our Uber drivers ( local males) warned us about the neighborhood confirming our unease from what we viewed ourself. They especially said it was not a good place to stay for 2 female tourists. After one night, we changed locations to a hotel by the water.... much more central. When visiting Lisbon, make sure to do your research beforehand.
