The staff could of been a little more pleasant during checkin like pointing out elevators, hotel amenities and dining options. Other than that, no concerns with room or parking.

Lovely place to stay - character, fun view of the neighborhood. Pretty noisy up until about 10 PM, but if you're looking for charm and character, this place has it in spades!
