It isn't a design flaw per se, as I'm sure the designer thought you'd pick a side to sleep on and not just go for the middle. :) My suggestion since you're going with an innerspring mattress, is to get a boxspring. Then you'll have even support all around and can better judge whether the mattress is right for you.

BB, I was just thinking of posting an update, so perfect timing. Yes the blasted post is gone baby gone! Here is the bathroom layout that ended up working the best after mocking up several different configuration. I actually will be able to fit up to a 48" vanity. The vanity and toilet bump back into the bedroom wall. Shower opposite with angled wall toward the entry to it. I am loving it! Ecko has already made herself at home on my couch mock up! This view is taken standing at front door. Here is the new bathroom layout. That line in front of vanity and toilet is that header beam above. I'm thinking about a flat ceiling with soft lighting over that area. But on bedroom side, that wall will go straight up to the angled ceiling. TV is going there. Not quite centered to bed, but good enough. Still a lot to do, but we are thrilled with everything. Everyone who sees it wants to move in! Thank you my GW fam! Pretty soon, I will be asking for finishes help!

I also think the house is adorable. Other than the tree needing pruning and the massively tall shrub on the right side (up against the house) needing to be removed (or pruned aggressively), I don't think the landscaping looks bad as a starting point. I agree with kiminpl that as newbies you should focus on taking good care of what's there and making small steps to improve it as time and money allows vs. trying anything too aggressive and ending up with something worse. If the neighbors live in massive homes, nothing you do is likely to make them happy. If that walkway really isn't being used (as it sounds like it's not), removing it could part of a phased plan. I personally don't think the right side needs another tree. Good luck!

whatever has been said..your landlord sounds like a real nice guy..:) unless of course you have agreement that your improvements hugely lower your rent? what I'd do though..if I was as handy and as eager as you.. -the mosaic in the kitchen where the backsplash is-hard to see whether a real backsplash or wallpaper? if wallpaper-get rid of it and repaint. if real mosaics-just repaint. ETA-ok reread your post..real mosaics. I love peel and stick options that do exist, but I'm not sure I'd go for them here..it's not so much mosaic as its placement..countertop backsplash plus mosaics plus wrap around..too much. And it won't be easy to find something that will work. But. Check your options. Etsy has pages upon pages of tile decals, for example. https://www.etsy.com/search?q=tile%20decals&ref=auto1&as_prefix=tile%20decals -you seem to have no space next to the stove..I know IKEA carries these narrow tables you know? or something of the kind..that you can put in between the stove and the fridge, have some landing surface, spot to place a pot you know -is the floor in the kitchen real tile or linoleum/vinyl? you can try and cover it with something if it irritates you of course(to me it's actually the worst offender. along with the blinds that I'd take out and put on curtains. but you're going to do that anyway). it can be tile decals, it can be floor cloth, it can be big inexpensive rug.. the rest of the kitchen, just deep clean and let be. new paint will make a huge difference -your door is fine..hard to see the living to make helpful furniture placement suggestion, but generally I find that sofa plus two chairs is the most versatile in most cases -the bathroom is cute and blue in cabinets picks up the flooring. Wallpaper is best to go though since it clashes with flooring. Clean the grout..and ask your landlord to change faucets etc if they're problematic. If they're not but you hate them-well maybe you can split the price. New paint, shower curtain that you love-and you're good. What's your style preference? I'm crazy about shower curtains so can look them up and suggest for you, and would be my pleasure:) you do need some "landing strip" as they call it..and I can't see whether youn can fit small dining table in the corner of the kitchen? .. if you want more suggestions about colors, furnishings, furniture layout and such, I recommend cross posting in Home Decorating forum. They(ok, us. lol) will ask you a bit more about dimensions, layout, preferences in style, budget, needs, etc. Congratulations on your first renting place, it's exciting..and good luck!
