Firstly...are you sure they are jarrah and not som other more exotic timber? If you are fortunate enough to have a genuine 1932 built cottage I say "Don't Do it!" Just look at the beautiful timber in that floor! It would be sinful to paint it. I have a 1924 cottage with beautiful hoop pine floorboards all from the day it was built. My suggestion is to have the boards sanded and polished. I would not even dare go near them with polyurethane. I have turned back the clock and used the methods of the period of the house...a mix of pale boiled linseed oil and kero. Put it on with a mop or a deck mop or a wool mop leave it soak in. Re-do and leave it soak in,,,( you won't get patches...the floors will just soak it up.) Third coat, add a bit of turps to the mix as a white ant deterrent. Then, when the floors look like they've soaked up enough, get a big old fashioned string mop...if you can find one...or use a deck scrubber and old towels...or even a wad of new ones...100% cotton...its worth it, and rub off as much of the surplus as possible...wear sox so you will notice when the sox do not get oil stained anymore. First go is a long process but you will be really pleased when the floors have had several "drinks". After that you could get just an ordinary floor varnish or oil or just a sealant. Some of the modern wood treatments are really good. Then, every so often do the boards over with your "Oil Mop". You will never find timber like that again and, in my experience, it adds to the value of the house big time. Do what you like to any gyprock and plastered walls but PLEASE love your floorboards and any natural timber...especially from that era. I've been in this old cottage for 32 years. Everyone wants to know where I sourced the "new" floorboards", and who did I get to make my silky oak windows! Hope that helps.

White-tail spider in my track suit pants WHICH I WAS WEARING! I thought it was a lump of lint from the laundry, drew it out, and promptly flung it across the room once I realised... never to be seen again! How it didn't bite me and sat still to be picked up, I don't know - it must have known I wouldn't do it any harm. We lived in lots of country places, too... We were invaded by small black crickets one year, and lady bugs, another year, in your drawers, in your hair, in your pantry, in your undies... everywhere! And then the blue tongue lizard that would go in and out with our dogs via doggie door, and made itself a nest in our laundry... I gave up and left some old towels for it. Had an echidna get up into the wheel well of our car... wild brumbies in our patio... the list goes on. My husband still says that the most unwelcome visitor was his mother... I like her better than he does!

Now you have posted this picture with an unmade bed and clothes all over it for us to see - note future girlfriend may be a houzzer. Number 1 make bed and put away clothes before guests arrive or you take and post photos as all the paintings and new doona covers in the world won't make up for this. After this consider all the great suggestions above. Note to self - make your own bed more often please rather than advising others to do same.

If you are in New Zealand, I have often found great lights (and a big range) at Lighting Plus. When I was putting my house on the market I put three of these: http://www.lightingplus.co.nz/lighting/pendants/contemporary/jaga-bcopal-1light-pendant.html over my kitchen benchtop, and they looked just gorgeous. So gorgeous in fact, that I have already bought three new ones in advance for when I upgrade the kitchen lighting in my new house. They also have these : http://www.lightingplus.co.nz/lighting/pendants/contemporary/hudson25-whitegold-1lt-pendant.html or these: http://www.lightingplus.co.nz/lighting/pendants/contemporary/trumpet35-pendant-blackgold.html  if you like the look of the internal gold under the shade. There are also others similar. I have also found some great lights at : http://www.edenlighting.co.nz/collections/pendant-lights . All of these are very affordable. However if you want to go really high end, and you like NZ timber lights, you can't go past : https://www.davidtrubridge.com/collection/lighting/  Just my 2c. Enjoy.
