Web query returns empty table

0 down vote favorite I'm trying to import data from a web page to Power BI Desktop. The URL is the following: https://casa.sapo.pt/Venda/Apartamentos/Maia/?sa=13 It contains data about housing prices, characteristics, etc. The query returns an empty table, although if I browse to the page with any browser and without authentication or login, I see it contains the data I'm looking to analyse so I guess the publisher has disabled somehow the query I'm trying to make. Does anyone know a workaround?
