How to join fixed row table against mapping table and reveal unmapped records

I have two tables and I am having trouble figuring out how to join them to meet my projection needs. Here is a scenario that illustrates the problem

1. The first table has a fixed set of values/rows; in this case Room Types

Room Types

Id | RoomType
--------------
1  | Bed Room
2  | Kitchen
3  | Half-Bath

2. The second table maps the items from the first table to an instance of a Property. One Property can have 1 or more Room Types

Property Rooms

Property | RoomTypeId
---------------------
  ABC    |     1
  ABC    |     3
  EFG    |     1
  XYZ    |     1
  XYZ    |     2
  XYZ    |     3

Note : some of the above properties are not mapped to some Room Types

3. I would like to make a projection that joins the rows in such a way that I can easily account for Room Types that are mapped and not mapped to a Property. Here is a sample result:

Property | RoomTypeId | PropertyHasRoom
---------------------------------------
   ABC   |     1      |      Yes
   ABC   |     2      |   No or NULL
   ABC   |     3      |      Yes
   EFG   |     1      |      Yes
   EFG   |     2      |   No or NULL
   EFG   |     3      |   No or NULL
   XYZ   |     1      |      Yes
   XYZ   |     2      |      Yes
   XYZ   |     3      |      Yes

Can anyone explain how this can be accomplished in T-SQL.
