Answer 1

This should do the trick:

In the callback of Array.reduce check if for the current element c one or more of the arrays in c.pt contain the search string.

If yes, add the c.hpid and the name of the properties containing the search string to the result.

units = [{
    'hpid': '787',
    'hpr': 'Hotel Apartamento Solverde',
    'pt': {
      'CONVERSION': [],
      'HOME_PAGE': [],
      'PRODUCT': [],
      'SEARCH': [],
      'SHOPPING_CART': [],
      'TRACKING': []
    }
  }, {
    'hpid': '130',
    'hpr': 'Hotel Algarve Casino',
    'pt': {
      'CONVERSION': [],
      'HOME_PAGE': ['/hotel-algarve-casino/'],
      'PRODUCT': [
        '/hotel-algarve-casino/quartos/quarto-standard-vista-avenida/',
        '/hotel-algarve-casino/quartos/quarto-superior-vista-mar/',
        '/hotel-algarve-casino/quartos/quarto-familiar-vista-mar/',
        '/hotel-algarve-casino/quartos/suite-vista-avenida/',
        '/hotel-algarve-casino/quartos/suite-vista-mar/',
      ],
      'SEARCH': [
        '/hotel-algarve-casino/quartos/',
        '/en/hotel-algarve-casino/rooms/'
      ],
      'SHOPPING_CART': [],
      'TRACKING': []
    }
  }, {
    'hpid': '300',
    'hpr': 'Hotel Casino Chaves',
    'pt': {
      'CONVERSION': [],
      'HOME_PAGE': ['/hotel-casino-chaves/'],
      'PRODUCT': [
        '/hotel-casino-chaves/quartos/quarto-standard-vista-avenida/',
        '/hotel-casino-chaves/quartos/quarto-superior-vista-mar/',
        '/hotel-casino-chaves/quartos/quarto-familiar-vista-mar/',
        '/hotel-casino-chaves/quartos/suite-vista-avenida/',
        '/hotel-casino-chaves/quartos/suite-vista-mar/',
      ],
      'SEARCH': [
        '/hotel-casino-chaves/quartos/',
        '/en/hotel-casino-chaves/rooms/'
      ],
      'SHOPPING_CART': [],
      'TRACKING': []
    }
  }, {
    'hpid': '759',
    'hpr': 'Hotel Solverde Spa and Wellness Center',
    'pt': {
      'CONVERSION': [],
      'HOME_PAGE': [],
      'PRODUCT': [],
      'SEARCH': [],
      'SHOPPING_CART': [],
      'TRACKING': []
    }
  }
];


let result = units.reduce((a,c) => {
  let entries = Object.entries(c.pt)
    .filter(y => y[1].includes('/en/hotel-casino-chaves/rooms/'));
    
  for (let e of entries) {
    a.push({ hpid: c.hpid, prop: e[0]});
  }
  return a;
}, []);

console.log(result);
