Better than expected. This new property was in a great location. Easy to walk to restaurants and shopping. Comfortable bed, nice bathroom and a sitting area with sofa, chair and tv. I was a little concerned because we could hear music from a nearby bar, but everything stopped by 10 o’clock. Would return.
