We spent 3 nights at Liliana's place. Positives: Great location in the heart of Lisbon and around many restaurants. The apartment is small and cozy, and there is excellent attention to detail like the kitchen well equipped, restaurant recommendations, etc. Our flight got to Lisbon very early, and Liliana was very accommodating. Negatives: As other reviews have stated, the noise can be overwhelming, there was construction next door (which started at 8:15 am), and you can hear everything upstairs; we had people walking from 5 am to almost 11 pm, and because it is an older building you can listen to everything. I brought this to Liliana's attention, and she did what she could to ask people to keep it down. Also, there is a smell of sewage in the main bedroom and hallway. According to Liliana, the scent is not specific to the apartment but the old pipping on the streets tied to the river.
Since this is a plus property and due to the price, I expected more, but this is an excellent place to stay if you can get past my negatives.
