No need to add curtains especially if they can't go to the floor.

Lower the painting about 6 or 8 inches. Right now it's lined up with the tops of the window and door frames--not good.

Take the mirror back--it's too small.

The book case can go as well. It doesn't belong in the dining room.

Add a centerpiece to the table. Maybe your pitcher with some pretty flowers.

The room could use a larger dining room table that doesn't so closely match the other wood. I would also suggest re-painting the room less yellow and removing the small table in the back left.

i'll disagree with leelee only about the bookcase. lacking another room to be a library, i find a library/dining room to be totally wonderful. but you might want to have 2 or 3 to do that wall.

you need a rug, and more art, and then you'll know what color to paint your space after you choose them.

oh, and you need a chandelier to come down over your table. if the landlord lets you swap.....? light fixtures can be really inexpensive AND nice looking.

You can swap out the fan for a chandelier and when you move swap back I did that many times when we were renters. Lower the painting so the center is at 60” I agree a larger mirror if you want one and a sideboard would be nice also an rug under the table would give the room warmth and also break up the floor and table color it will have to be big enough to allow the chairs to still sit on it when pulled out usually about 2.5 ft. bigger all around than the table.

Add an area rug and chandelier - you can take both with you when you go. Paint below the chair rail if allowed. Perhaps a centerpiece of some sort on the table. Forego the curtains, the woodwork is very nice and you don't need them for privacy.

The room is swallowing the table. Change the chairs. Pick-up different chairs at a flea market or yard sales. Add an area rug. Or turn the table side ways. Good luck!

May I ask what are the dimensions of the dining table?

1 roman shades on windows

2 dig mirror on the wall behind the sideboard similar to http://sainteriordesignstoronto.com/treasured-moments.html

The room needs fabric. I would use shirred panels in the windows; move the drapery rods to one of the longer walls and hang tapestries. Table runner, tall potted plants; an area rug if the budget permits.

If the table is small for the room, consider running it the other way and adding a focal point by the entrance, like a table or small seating area, or just leave it open for a more spacious feeling when entering the home.

anecpenny - have you considered putting up paper shades? they can be bought fairly cheaply at HD and other places - or online - at about $6 per shade. There's a strip of adhesive at the top that holds it to whatever (and doesn't damage the substrate) and you can cut it to fit the width of your window. I used these all the time when I was a renter - they were a life-saver! And they don't look bad; the clips to hold them up don't exactly look high-end, but it never bothered me enough to want to buy blinds or shades for the landlord ;) The brand is "Redi Shade" and they come in various levels - from light-filtering to light-blocking. Might be worth a look.
