Not much to add, really. I believe that being returning visitors (we had stayed at the other flat, across the hallway) says it all.
As previously, we are extremely happy. The flat, the location, the quiet, yet 7 minutes walk from the metro, buses, and Lisbon's main artery, Av. da Liberdade. There are also a couple of delis, restaurants and cafés 5 minutes walk from the flat. And Patrícia and Arthur are their usual selves, welcoming, chatty and very helpful. Can't recommend highly enough.
