Overall we had a great stay in this apartment. Sone points I want to emphasize:
(+) Big plus: The communication with Claudia who was always reachable, helped us as good as possible and gave us tips around lisbon.
(+) Check-In and access to the apartment is managed by a webapp, so no physical keys are needed.
(-) The second bedroom does not have an outside window. The main bedroom is right above a heavily trafficked road, so it‘s always kind of noisy.
(-) The "private terrace" is shared by at least two other apartments in the complex and is sparsely equipped
