Castle Kearan is an amazing stay! Marie and Bobby are wonderful hosts — very responsive and want to make sure you enjoy your stay. The Airbnb was completely stocked with anything you could need. The bed was very comfy with soft sheets. Everything was very clean and organized. The neighborhood is quiet and safe. We would be happy to stay here again!

★★★★★
Super clean and really cozy, which made it easy to relax after being out all day. Away from the busy streets so nice and quiet, but still close to everything we needed. Our hosts were nothing but kind and hospitable. The only negative was having to leave.

★★★★★
Marie and Bobby were the best hosts — super respectful, comfortable and spacious for 3 of us. They gave us more than we needed and made it feel like home. Marie responded instantly when we needed her. I definitely would stay again!
