Location: anything but hotel. There are cameras everywhere. And the hotel staff almost always knows what's going on.
Parking: safe, easy and plenty of available spots
Directions: clear! A picture is worth a thousand words.
Neighborhood: safe
Cleanliness: nobody likes walking on sticky floors or stepping on things
Amenities: if shower and toilet are not available, explicitly mention that

Clean towels and cold drinking water would be a nice touch.
