The apartment is in a great location, near to a metro line and near to some free elevators (as opposed to the Santa Justa elevator which has costs and, usually, a queue) in the shopping center that is only a few steps down. The pub on the ground floor is a good option for a beer if you've tasted enough wine for a bit, and perhaps more importantly did not cause any problems whatsoever with noise at night
The apartment itself is well furnished and has what you need to not only relax there but also prepare meals if you'd like.
The pictures clearly show this, but the slanted ceilings do take away a significant amount of usable space. Not unexpected but also not to be underestimated.
All things considered, I would stay in this apartment again.
