Okay, I know some folks are not too enthralled about the sleeping arrangements, here are the latest details from Christine the landlord:-

Glad to hear you recieved the details.
One week will be 900.
You will see there are 6 beds,but 3 are doubles, if its not acceptable to share a bed I could provide 2 single beds in the dining room, maybe a mattress in the lounge if needed.
Looking forward to hearing from you.
Regards Christine

This could get us to 9 beds if we need that many.
