The apt is close to the party places of Bairro Alto and Principe Real. It is on the famous 28 tram network. Note: Uber will not drop you at the doorstep as it is a kinda private road. They will drop you on the main street 1min away. The unit number mentioned was incorrect, but was quickly clarified. The neighborhood is pretty quiet and is close to everything you need. Closest metro is Baixa Chiado. The neighborhood is very touristy. There is a very cool miradouro close by.
The apartment is a very basic barebones ikea furnished apartment. All the furnishing is very basic and not comfortable. The bed thankfully was comfortable. The vinyl flooring was quite noisy. The apt does not come with a TV for some reason. The kitchen is well equipped. Hot water was good. I could hear the people above walking.
Overall the location wins if you would like to be close the fun part of Lisbon yet in a quiet neighborhood. But the furnishing, etc are just very basic.
