 $query = "select FROM properties where property = '$property' & bedrooms = '$bedrooms'";

Answer 1

Try this instead:

$query = "SELECT * FROM `properties` WHERE property = '{$property}' AND bedrooms = '{$bedrooms}'";
$row=mysql_query($query);

Your sql is malformatted and need to execute the query.

Answer 2

You forgot to execute your query!

<?php

 require 'defaults.php';
 require 'database.php';


 $property = $_GET['property'] ;
 $bedrooms = $_GET['bedrooms'] ;

 $query = "select FROM properties where property = '$property' & bedrooms = '$bedrooms'";
 $result = mysql_query($query); // <-- You forgot this
 while ($row = mysql_fetch_assoc($result))
 {
    $r[] = $row;
 }

 ?>
