Catarina's and Antonio's apartment exceeded our expectations. There was three of us but the place could easily host four people (perhaps even five if there's a kid). The couple have done miracles with the renovation and the place is so clean and inviting you couldn't ask for anything more. They both did everything to accommodate all our needs and they made us feel really welcomed.
Its location is so convenient we just walked everywhere. We loved Lisbon and we loved Catarina's and Antonio's place - we'll be definitely going back first chance we get!
