Therefore; if you are decorating a home using the influence of Mid Century Modern, or Modern, you wouldn't need to be as careful, but would be looking more toward getting that vibe, with new colors and furnishings that are currently popular but influenced by that era. 

You could place something decorative there (glass, an adhesive, artwork) to give the viewer a sense that they are looking at or out a window. 

That would be a tank big enough to decorate, have multiple fish to watch, etc.  

"Reclaimed" wood is all the rage in furniture and decor right now.The diabetic strip thing has been discussed here before.  

I've decorated my places like Hugh Hefner's mansion.  2000 previous renters and no complaints 

6) Other activities, general operation of the building, landscaping, cleaning, etc.As far as landscaping, cleaning, decorating, I think these can be farmed out pretty safely to outside vendors on a monthly subscription so that no input would be required on my part in order to maintain the property on a week to week basis.

December-January, we decorate our 8-plex with white "holiday lights", which really makes it cheery when coming home on dark winter nights.  

For example the one that I live in I put in no pets, no smoking, no sublet, no waterbeds, no inflammatory speech displayed in window,  can't use the roof, decorations must not destroy walls. 

The house looked fantastic with his decor.

In addition, we put decorative curtain rods in the living/dining rooms.
