Pros: Very large rental unit in a very convenient location, just a few minute walk from Baixa-Chiado station in the heart of Lisbon. The kitchen is well-equipped and bedroom is quite spacious. Check in was relatively seamless.
Cons: The bathroom does feel somewhat dated (older grout-work, small tile missing on the floor, okay cleanliness).
The unit can get quite warm with the windows closed, however the street can be a bit noisy so depending on the time of year you may have to choose between being a bit warmer or dealing with the noise. A fan is provided but there is no AC.
It is managed by a larger rental group so you may not get the same personal touches that you would get with a personally rented unit.
