Great location, right in the heart of many bars and restaurants. But very walkable to the river, great shopping and many historic sites. There is a very active nightlife right down in the streets below the flat. But when we were inside, we were not bothered by any noise from the street. The flat itself was nicely appointed and we were kindly left a nice bottle of wine, some chocolates and sardines. It was a really nice touch.
I would highly recommend this place to my family and friends any anyone else visiting Lisboa.
