We stayed in this apartment 4 nights in August 2012 and it was a very nice apartment, right in the city center.
The only problem with it is that you need to climb a lot of narrow stairs to reach the appartment (it is on the 5th floor) and that one of 3 the bedrooms doesn’t have windows. But, anyhow, the view is amazing and it has a well equiped kitchen.
The owner is very nice and helped us with a lot of useful information. The downstairs restaurant, which is owned by Bruno, is a good place to taste a real portuguese food.:)

Thanks, Bruno!
