Dilemmas!!

It's my 3rd day in Inverness, and I have seen all of the 7 house shares that I had lined up. Of those 7, 2 are pretty crap, 1 is ok, and 4 are really good! So now I have a difficult decision on my hands. The problem is that each of the final 4 has good points and bad points, which makes it quite difficult to choose, but I need to make a decision before Monday really, so that I can let everyone know! So, I need your help! Here are the choices:

Option 1
£330 per month, with £330 deposit. All bills included in rent.
Nice modern house, shared with 2 females in mid 20's. My room would be the downstairs double bedroom. Also have use of kitchen/dining room, bathroom and living room (upstairs). Decking outside as garden.
10 minute walk to RSPB office, 30 minute walk to town, but bus stop close by and regular buses.
The room is currently occupied, so the earliest I could move in would probably be Monday/Tuesday.

Option 2
£380 per month, with £380 deposit. All bills included in rent.
Nice, quite large modern house in fairly new area. Owned by couple in late 20's, husband away on business all year but visits on weekends. Wife will often be visiting him as well. My room is good sized double room, which she will repaint sometime soon (so may have to move out for a few days while this is done). Also have use of kitchen/dining room, living room and bathroom. Fairly large garden.
30 minute walk to RSPB office, 45 minute walk to town. Bus stop close by, but only 1 bus per hour.
Can move in any time.

Option 3
£360 per month, with £360 deposit. All bills included in rent, but no wireless internet, although she will consider getting this.
Nice, old, large house very close to city centre. Will share with 1 female in mid 20's, whose boyfriend often comes to visit, and she will often be off visiting him as well. My room is good sized double room, no wardrobe, but plenty of storage space eslewhere. Also have use of large kitchen/dining room, living room, WC and bathroom, which will be replaced in early May due to crack in bathtub - may mean moving out for a couple of days while this happens, or no showers for a couple of days. Smallish garden.
20 minute walk to RSPB office, 5 minute walk to town, all buses go from town centre.
Can move in anytime.

Option 4
£360 per month with approx. £90 deposit. All bills included in rent.
Nice mid-sized house in ok area. Will share with 1 female in 30's, but is often out with hobbies. My room is good sized double room with loads of storage space, and TV with freeview! Also have use of lounge/dining room, kitchen and bathroom. Front and back gardens.
15 minute walk to RSPB office, 25 minute walk to town, buses stop nearby and are regular.
Can move in anytime.

So all quite similar really! Which probably makes it harder to make a decision. Option 1 is cheapest, Option 2 is furthest away from everything, Option 3 is the oldest house, and Option 4 is average really. The house mates in all cases are really nice, so just need to decide! What is your opinion?? Help!
