We (2 adults, 1 child) stayed 2 nights and really enjoyed it - the place is spacious, clean and beautifully designed, also the location is great - central but quiet and lots of cute little restaurants to be explored in the tiny streets around it.
In walking distance to the Tejo.
There's a great list of personal recommendations at the place (which we studied on the sunny terrace) and you also the famous Fado restaurant "Sr Vinho", just across the street.
Tomás friend Miguel checked us in, really friendly and also gave a lot of tips.
The bed in the master bedroom could maybe be a bit more comfortable, but all other beds were totally fine.
