Brest is best
Nice yard, nice BAR,plenty of boaty stuff on site. The local bus service into town is(or was) free and has pickup outside the main supermarket.
Most of the venders on site also speak good English if you speak bad French.
We had Piper lifted out at Cameret. There is a 15t fixed crane and excellent DIY boat wash area. You can stay on board while the boat is out and you are close to all the town facilities, but the marina toilets and showers are about 800m away. There are good engineering services available. As the crane and boat wash are new they are offering very cheap rates. It cost us 80 euro for the lift out DIY pressure wash, 4 days ashore and the lift in.
Moulin blanc will lift and transport the boat up the road to a number of yards for storage which works out cheaper sometimes. Good work from latitude sailing or benoit lucas.
