Great apartment in a very central location. High ceilings are lovely and the floor to ceiling windows are stunning. Well-decorated and well-equipped for a long stay (I was there very comfortably for a month). Wifi super fast and bed comfortable (although worth noting that it's not one large bed, but two single beds pushed together). It could be loud outside, but the windows were double paned and incredibly soundproof when shut. Location is very central and great for tourists who are looking for easy access to the landmark Lisbon attractions. Definitely a building of holiday rentals, meaning that you were at the mercy of a rotating cast of neighbors and their respective noise levels.
Erina & Mariana were very responsive to my communications and were able to help with any and all questions I had. We had a really smooth check-in process and they accommodated my early flight arrival time without issue - super appreciated.
