Overall, the place is neither amazing nor terrible. It will be a good match for some, and a bad match for others.
First, the positives:
- Internet was around 100 Mib/s up and down, and the WiFi coverage was very good.
- The location is extremely convenient to the Chiado metro, restaurants, and nightlife in Bairro Alto.
- Unlike many places in the area, it has an elevator so you don't have to drag your luggage up many flights of stairs.
Now for the not-so-nice parts:
- The apartment is OK, but "luxurious" is really a bridge too far. It needs minor maintenance (e.g. missing bathroom tile, broken toilet paper holder, non-functional hall light). The mattress and pillows aren't very comfortable. There is a single floor-standing fan that is falling apart and won't point anywhere but the ground unless you wedge things under its legs.
- There was a large baby crib eating up most of the empty space in the bedroom.
- The location is extremely loud, until 2 or 3 am, including weeknights. The noise isn't bad with the windows closed, but then the place gets very warm. So if you want to sleep before the party outside ends, you have to choose between roasting in silence or being reasonably cool with a lot of noise. Obviously this wouldn't be an issue in colder months.
