It's a simple room off the back of the house with its own separate entrance. The bathroom is shared, but the arrangement makes it feel essentially like a private bathroom.
Everything was clean and as-expected. The location was great - I had a nice 25 minute walk to my office and then was able to walk & run to the beach, which was only about 20 minutes (walking) away.
I only had a one-night business trip, so it was perfect for me. I would definitely stay again.
