We had an overnight stay here for a last weekend away as a family of 2 and it exceeded our expectations. In a pretty good neighborhood, in good distance to everything around we wanted to do. The amenities were great, we didn’t get to experience the bar by our own choice but it looked fun too! The breakfast options were great and delicious, the waffles were A+.
