At the airport when you fetch the hired car it will be useful to ask to the rent a car people to show in the map where Ponta do Pargo is situated and which roads you are ought to follow. This will help you a lot together with my indications.
Once you are ready, drive out of the airport towards Funchal city through the dual carriage way so called "via rápida", you need to drive straight ahead until the end of the via rápida in Ribeira Brava village. It will take approximately 35 minutes driving from the airport to the end of the via rápida.
On the last tunnel, keep on the right hand side lane to descend the valley of Ribeira Brava village towards the sea. After driving roughly 5 minutes, you will encounter a round about with a tunnel on the right hand side that you ought to follow. From this tunnel prepare yourselves for a succession of tunnels and round abouts that will make you pass through the following villages: Ponta do Sol, Madalena do Mar and Calheta village. Remember to drive always towards the West end of the island and near the coastal roads by the sea.
After passing Calheta's round about continue straight ahead through an other tunnel and keep driving through the small villages that you will encounter on the way. They are respectively: Prazeres, Maloeira, Raposeira, Lombada dos Marinheiros and finally you will come to Amparo village where the apartment is located. You can not miss it because you will recognise the house and the supermarket/bar from the photographs portraid in the pictures. There will be someone waiting for your arrival in the bar to welcome and greet you.
