That's what we did. We booked into the Harman for a week thinking it would be easy to find somewhere furnished and move in straight away.
This was after leaving our jobs, having a big leaving party and arriving with 20kg of luggage each!
We ended up booking an additional week in the Harman, by which time we were all sorted albeit with an unfurnished house.
We did lots of homework first, with masses of help from people on this great forum.
You'll be fine!
