It's a bit difficult to find a good map for the consulate, chiefly because the building is defined as being four storeys.
It may be best not to include a map so your players don't get the impression that the embassy is going to matter later on in the book; that there might be combats there, that they might need to return (assuming they made a clean sweep on their first visit).
I would suggest drawing a more 'symbolic' map. Create boxes for key locales- 'hallway outside Ambassador's room', 'ambassador's room', 'reception', 'room with Nilasa's body', 'the fence- and encourage the party to add notes onto the boxes. 'Clearly didn't jump from this window', 'we aren't allowed in this room', 'brigadeiros?'
