Appartement of Ben and Lena is just wonderful- beautiful, great location, friendly and helpful hosts. From the balcony you can see the towers of the cathedral, Praca de Commerco is just 2 small streets away. Just fantastic. The only thing you need to be aware of is that this is 4th floor no lift. But if you plan to visit Sintra, it us just a good practice to climb few stairs. I recommend fully!
