Accommodation. Why is it so hard!

Maybe I'm just being too choosy.

What I want is somewhere convenient for Welwyn garden city (ideally train-able or even better - walkable).  That does give a decent selection of places.  Also must have somewhere to sit, somewhere to cook, somnewhere to shower and somewhere to park.  Ideally also a desk.  I'm sure that's not asking too much.

The thing is a lot of the nice looking places aren't available until 8th August. 

The first place I saw was perfect. Sadly there was a lot of interest so I didn't get it.  Arranged another place but the owner decided to let it to a friend.  Emailed several places (most people don't give phone numbers) but don't seem to get a lot of replies.  Looked at a couple of places today.  First one there was no answer.  Second I felt I'd get very lonely and miserable there.  It was a huge place where I'd be essentially on my own.  Been there.  Done that.  It's very miserable. 

I can afford hotels for the entire duration of the contract if I must.  Would rather not but I can afford to be a little choosy.
