Although we didn't feel that the apartment matched the pictures or description in terms of being a "luxury" listing, it was fine for our last night in Portugal. The building is old and so things are loud (the elevator, the water system) - totally understandable, but just FYI. There are "you break it, you buy it"-type signs posted in the apartment, as well as posted admonitions not to use the air conditioning...which felt a little like being in a college dorm, not a high-end Airbnb! The street noise is also a little loud, but this can be mitigated by closing the window shutters. Communication with host was a bit odd but we got things figured out. Also FYI - as of Feb. 2020, Google Maps puts this in the wrong location on the map (although the listed address is correct), so go by the address, not the map.
There's nothing specifically wrong with this place, and it does provide a very central location with good views and three bedrooms - a rarity! So if you're looking for a no-frills, centrally-located place with three bedrooms in Lisbon, and don't mind a little noise and a little lack of charm, this would be a good place for you.
