A great authentic experience away from the overcrowded and touristy parts of Lisbon; I highly recommend O Dom Nogueira for food. Just be aware, there are TWO streets of this name in Lisbon, make sure you put the one in Pontinha into your satnav.
Teresa was there to greet us, the flat is very clean and a nice size for four people. There is free on street parking, though finding a space could take a bit.
