Growing up, Mother has impressed on my sisters and I the importance of making the house feel warm and welcome to visitors, especially relatives.
There’s never too much that can be done. The first thing that our mother considers important is the bathroom: at the present moment we have two bathrooms, one in the master bedroom and the other for the children's use. With seven children using the one bathroom, it is not going to be presentable at any given moment! When we know we will be hosting visitors, we zoom in on this particular room and clean it from top to bottom. In our present house it is especially difficult (not being all the way finished out), and we must excert all our powers to make it look presentable and sweet-smelling. One way to make it smell good, is to place a candle or two on the sink, etc. after cleaning the bathroom. This gives the room a warm, comforting and pleasant fragrance to the visitor. This works better than spray, I think, as you don’t have to keep spraying periodically.
Of course we vacuum, if needed, the living room and any other room that will be used; since ours is relatively small and gets dirty quicker, we do it every time. We like to place a special tablecloth on the dining room table if it is in view, and maybe some flowers in a vase if available.
Lighting: In the winter, low lighting is very comforting and warming. We really enjoy, even in the summer evenings, turning on a string of “Christmas” lights we have strung up around the living room year-round, and turning off the main light. It gives a nice glow, is just enough light to be able to see by, and calms the mind.
Besides making a visitor feel welcome in the house itself, there is the physical fulfilment part.:) A visitor should never have to ask for anything. When anyone comes over, even for a short “drop by” visit when they sit down and talk, we try to first give them something to drink-- if there is a choice, we’ll ask, but if not, we’ll just set it down in front of them. We also try to set out a snack just as a matter of form. It could be chips and hotsauce here in Texas, trail mix, or other simple, easy fingerfood.
I hope this helps. Entertaining visitors is fun, and on such occasions as dinner parties and such, each doily on the coffee table or extra dusting makes visitors feel they are special--which they are! Most of all, put on a happy, joyful countenance and make them feel that you welcome them!
