We've stayed in Lisbon before. This apartment is in the best location! You get 2 beautiful balcony views as it's on the top of an authentic old building. Its close to a "miradouro" (lookout over the city) where everyone hangs out.
The place is so cozy and romantic. We arrived and it was spotless and super clean and fresh. We stayed there with a baby and were received very well. The hosts are wonderful and communicated very quickly. I highly recommend staying here.
