I did a 4 week initial in BH and chose to live in the Thistle Brigton, which is acceptable and surrounded by lots of good food choices.
Did not like (over)paying for the in-hotel parking, so I bougt a 1-month card at a nearby multi-story and saved a few bob.
The drive to CAE from the center of Brighton never took more than 25 minutes, no isue really.
Hope this helps.
