Two of us stayed a week in the apartment during mid September. The place was exactly as advertised and our host (Catarina) was wonderfully helpful. Communication was excellent. The apartment is on the 3rd floor (4th floor for North Americans) and can be accessed by either stairs or a nice elevator. The AC in the bedroom and living room functions well and is quiet. There is one apartment above, and we could hear movement upstairs every morning between about 7 and 8 am. This wasn't an issue for us, and entirely expected in an apartment building. The road out front is currently closed to through traffic, but it remains accessible to vehicles and taxis. This closure means there is virtually no traffic noise, although the lights on the Banco Portugal building across the street keep the living room (and thus the sofa bed in the living room) quite light all night. There is nearby construction (I think they are expanding the metro lines), but we could not hear any noise from this construction. There are many nearby restaurants and I recommend making reservations a day or more in advance for the popular (i.e., good) ones. Overall, this is wonderful place and I would definitely stay here again.
