More breakfast selection, but still good.
6 / 10Average·May 2025
The location was great and it’s a newer property. We stayed for 5 nights while visiting family.
We asked for cleaning and it was unreliable and confusing. They do something called a “refresh” instead of cleaning. Signage in the room on this would have been helpful. The mattresses need to be turned as well as ours had an indentation.
