This apartment is walking distance to most tourist sites. The apartment is very spacious. It is located on a tram line but you only hear the tram in the living room. I did not hear any noise in the bedroom. It is very quiet.

The apartment is modern, spacious, clean, and quiet overall.
There are only two issues that may be a concern.

1) the internet in the bedroom is non-existent.
2) it is on the 5th floor (the main floor is counted at zero) and there is no elevator. This is only a problem when moving in and out. We were helped with our baggage on the way in. We managed fine on the way out. It is always easier going downstair.

Despite these small criticisms i would highly recommend staying here. It is a great home base from where to see Lisbon. It is a pleasure to come home to this place after 12 hours of walking and sightseeing.
