Wow that really stinks that you got sick!

And I would definitely write a letter about the "room invasion" if I were you. Even if they HAD had the right room, they should have returned everything to the state it was in before you returned. I would be embarrassed if I were that maintenance person, honestly.
I don't think it would hurt to compliment Isabel in your letter, either! If you mix a little positive with the complaint, you might get a better response!

(Plus Isabel obviously deserves the accolades!)
I LOVED your TR and I can't wait until you go back so I can read another one!
