When ever I have guests come over, usually family and usually my mom. I like to make sure they are comfortable. So this is what I do to get it ready. Beside the usual things like clean the sheets and dust the room. I like to add some special touches.
Put in fresh flowers and reading materials. My mom is like me and likes water by her bed so I make sure there are coasters.
Place a robe incase your guest don't want to come out in the rest of the house with their pjs on. And also a hook for hanging clothes.
Clean towels so they don't have to search for them and some snackies incase if late night munchies ( nuts and grapes) or what ever I have.
Sweet welcome note.
Also make sure they have a light by their bed incase they want to do some late night reading or need to see to get up out of bed. I think having a mirror even a small one is good too. Just so you can check yourself before you join the rest of the house hold or without making it to the rest room.
In the restroom I make sure there are extra wash cloths and toiletries. This is a great time to use all those travel things I get from hotels.
That is pretty much it ...what do you do to welcome guests?
