I've done this the hard way as well.
I used to live in a Studio Apartment - in LA - 970 a month.
It wasn't much, and I slept on the Futon in the middle of the room (could not even affrod furniture at the time).
I meet this really, very, very hot chick - and to say the least I was somewhat concerned about bringing her home to my place - so I avoided it for a while - but eventually has to do it.
Not a problem - she actually like my place, and stayed there most nights - and we ended up having a 5 yr relationship.
I think a coupole of things.
1) Make sure the complex you live in is clean and well maintained. Neighbours tell a story about the place itself.
2) Clean, Clean, Clean.
3) Toilets are a big deal - especially the shower. Make sure it's scum free and clean
4) Put clothes away. You can buy handly organzers for closets etc. that are cheap and easy to install. It goes a long way to store your items and not have them stacked in a room or corner.
5) Magazines and photo's (of yourself/paces you've been things you've done)
6) scents. you can by fresh scents from any store - don't go overboard.
7) Comfort. Make sure your place is clean and organized - but also lived in. A place that's to 'put together' is not comfortable. You want a woman to feel like she can kick of her shoes and lounge on your sofa.
