Several years ago, my parents moved into Lenbrook. They stayed for a short time, until the cost of assisted living at Lenbrook became too expensive. As a result, my parents moved into a smaller assisted living community with excellent service where the fees are more reasonable. Lenbrook is definitely a "luxury" retirement community -- and it comes with a luxury price tag. The entrance fee is pretty steep and the monthly fees can be draining, depending on the type of assisted living that's needed. If you have the financial funds, it's excellent. However, if you have a monthly budget, then I would look at alternative options.
Having said that, the amenities and location are excellent. Lenbrook is located downtown (Buckhead) and close to shops, restaurants, art events, nearly anything you could want in downtown Atlanta. During my parents' stay, they occupied a large room with a beautiful terrace (where my mom could garden and attend to her plants). There were plenty of activities and events for residents, and everyone was quite friendly.
