This apartment is brilliantly located for everything! The Metro is being extended quite locally but it did not have any impact on our stay at all.... no noise, still easily accessible.
The apartment is safe and secure and comfortable and the check in and out was made very easy for us thanks to Pedro and Susanna's great instructions. From the airport, get the E metro to Trindade and then the walk to the apartment is VERY straightforward ( less than 10 minutes)
The apartment is unusual and is in the traditional Portuguese style, making it far more interesting than a modern flat.
Highly recommended!
