More than the aesthetics of it I would say that it is more important to consider the practical placements of it. Some keys points:

1. It should not be in area where strong/direct sunlight can get to it. Common sense here since sunlight = heat, heat = aircon need to work hard. Sometimes sunlight can also decolor the aircon unit.

2. Not too near to lightbulb/light source. Same reason, light source often emits heat, which will confuse the aircon thermostat in detecting a higher room temperature than it is, then might give you cooler temperature than the one you set
