We loved our stay in this apartment. It is very well equipped and renovated to a high standard.
Location is amazing if you want to stay in the middle of the medieval town, which we did ( as apposed to staying in the actual city of Lisbon).
The apartment is right in the middle of a "square" which at night the locals come out and cook food and play music and sing till late at night (remember the sun doesn't go down till 11pm anyway). The double glazing windows are fantastic and the noise was not a problem.
Our host Miguel met us at the front door. Was very obliging and gave us a lot of information about transport, local attractions, restaurants etc.
