About 2 years ago I took a job at a startup. The hours were long, the pace frenetic, but the mission was amazing; truly a once in a lifetime opportunity. After that opportunity concluded, I resolved to find a peaceful spot in Maine to recharge my battery and reconnect to myself in between jobs; which is how I ended up on Joanna and David's doorstep one Sunday for a weeklong stay at the Blackberry cabin.
There are many things to commend the cabin, and the retreat more broadly to you if you are seeking peace. Joanna and David provide fabulous hospitality (they delivered fresh vegetables from the garden to us several times). The retreat location is essentially equidistant from Bar Harbor and Winter Harbor; having spent a week previously in Bar and Northwest Harbor I was astonished at how remote and gorgeous Winter Harbor is on a long run. the Retreat itself is fantastic - there are plenty of fun things to do right there, be it swimming in the quarry on summer morning, canoeing in the quarry, enjoying the amazing wood fire sauna, or standing in the stone garden. To my mind, the retreat is the ideal place to go if you want to be close to Bar Harbor but not TOO close; it affords you the option to explore more remote, less bustling (and commercialized) parts of Maine while also allowing for you to go nowhere at all.
I would be remiss if I didn't note that David and Joanna have gone out of their way to shape the natural beauty of the area to foster a harmonious space. David in particular seems to have a deep affinity for stone that I've not encountered anywhere else. If natural beauty is what resonates with you, I'd encourage you to consider a stay here.
