Super nice stay, clean room, everything up to date. Shower was hot with great water pressure. Slept great on mattress and pillows. Excellent service, and loved the donut shop attached. The one issue we had was no microwave available anywhere on the premises to reheat leftovers or warm my toddler’s lunch. The front desk claimed there was no microwave for us to use anywhere. Very inconvenient for my child.
