Nice apartment for no more than 3 people, 5/10 minutes away from the train and metro station. As pretty much all the northern area of Lisbon planes fly over every 10 minutes so keep this in mind in case you want a super quiet house.
A few things could be improved, the house had not been properly cleaned when we arrived but maybe we were just unlucky and the host promptly fixed the issue, he was very nice.
Overall a nice solution for our week in Lisbon
