What a great location overlooking Figueira square. The room we had, 305, was very spacious, (almost suite like) clean modern and bright with excellent views of the square and great air conditioning, which was needed during our visit. the complimentary bottle of wine was a nice touch.
The staff were friendly and very helpful. the breakfast was light and just what you needed to start your day. You will be asked to book a half hour time slot for breakfast.
As noted in the description, there are no lifts. the reception is on the second floor, we were travelling through Portugal for two weeks, so had two heavy bags of luggage. So I had a bit of exercise at the start of our stay and at the end. I didn't find it a problem and if you are travelling light, it won't be an issue.
It's a city, so expect a bit of street noise. We were there over a few days of one of the Portugal world cup games, so there were lots of fans about. I slept well in the comfortable bed, so barely noticed.
