The location and the building aesthetics - minimalist modern aesthetics - were fantastic. Although on a very lively pedestrian way, the quality of the windows dealt adequately with the noise. The apartment layout was clearly designed by an architect, with open living/dining/kitchen area and the 2 bed rooms with maximum privacy and each with very pleasant and attractive en-suite bathrooms.
The lighting in the apartment on the whole was far less than adequate, however. Very dim in the bathrooms, and in the LR DR Kit which is contiguous single space.
Elevator was broken for 3 days during my 7 day stay, a major inconvenience.
But I do think the apartment is a superior choice. It definitely contributed to our pleasant experience of Lisboa.
