If you are in Lisbon for the first time and wanna stay somewhere at the 'centre' then I'd recommend this place. A lot of tourist attractions can be reached by foot. And I was there during the pandemic. They had taken full care of hygiene: sanitizer at the door, separate bathrooms for different sets of rooms. It was easier for me maybe also because the place wasn't crowded (less travellers due to the pandemic), nonetheless, it's a good place to stay. And people in the reception are available even via text message if you need help getting around the city. Maybe there are better places, but being in Lisbon for the first time, it was a nice place for me.
