It's kind of a rip off.
There is a bed in the servant's quarters for you. That's.. about it.
Did he not treat us like a servant though, even though we never had to make him a cup of tea. Apart from one very nicely worded bit of grovelling to get us to do something.
Edit, eventually found it.
Neloth - Have you seen Varona? I'm hungry
Aussie - No, I haven't seen Varona.
Neloth - Well find her, tell her I want apple cabbage stew with some canis root tea
Aussie - Hey, I'm not your servant
Neloth - Obviously not or you would have a cup of tea in your hand. I suppose you want to be asked nicely. Very well.
Neloth - Please oh hero of Skyrim. Please find Varona. I shall be ever so grateful.
