Apples and oranges

I have read 3 papers, searched 4 online sites and gone through the list from the Hochschule, called about 40 places, seen 5, and narrowed it down to 2. How hard can that be? Well you try to figure a weighting scale for these:

1. small 2-room loft very close to work
+ cheap EUR210/mo + ~90 heiz + uzw => ~350EUR inkl.
+ my own place
+ all white, very bright with 3 big double-paned opening windows (parallel to roof)
+ can do anything I want to the place because he is renting it unrenovated
+ laundry room in basement
+ don't think there is any problem with having a dog - all linoleum floors
+ across street from playground/park with trees
+ near kino, burgerpark, ethnic grocers, kebab shop (yum)
but
- not a stick of furniture, no appliances, not even a kitchen sink
- 8 narrow flights of stairs to 4th floor
- car-oriented area - near busy intersection, probably too noisy to have window open all the time

2. big shared loft in St. Johannermarkt
+ fantastic area, all pedestrian, very lively, but in quite corner away from main plaza
+ had fun over glass of wine with roomie, liked her at first meeting
+ huge room, east facing window (+ west-facing window across hall if door open)
+ new washmachine, about to have complete new kitchen, only need to furnish my own room
+ own washroom/shower, very long hall to entry, then living room/kitchen, other bedroom at far end => private
+ west-facing terrace in back of buildings, very private
- roomie is paying for all upgrades to her new apartment, and considers she is more entitled to space generally
- bit expensive maybe - 400EUR inkl. (but less than half lease, because she has better accommodation with sauna
- not my own place, would feel like I'm renting a room in someone else's home, her furniture in main room, etc
- roomie is young professional 25 (but not a party animal apparently)

The criteria:

1. solitude
2. light
3. quiet
4. ownership

hmmmm...
Still tough - really wish I could find a single apartment in St. Johannesmarkt, or at least quieter street than #1. Need to use genetic manipulation to combine #1 and #2. Solution: call another one ... ah, Nauwieserviertel! That's near St. Johannesmarkt!
