    “One of the best things is having my own kitchen. I often end up working late and I don't fancy eating in a restaurant on my own, so cooking for myself is a big drawcard. ”

    “The main thing for me is being able to cook and have my own little flat. The staff are amazing. It is great to be recognized by them, ”he says.

Pauline Robinson

As a woman staying on my own, it is reassuring that they look out for you, and recently when I was poorly they even brought things I needed to my room. ”

Ryan Ruckledge

    “The fully-equipped kitchen is great. I always have a one-bed apartment so I have a separate kitchen and dining room and I'm able to relax and cook some meals. Eating out can feel a bit much when you do it day in and day out—it makes you hate what you do—and I don't want that.
