The tile installer should have used matching caulk, which is flexible, but he took the easy way out and used grout, which is brittle and crumbled. Use painting tape to protect the tile and counter and apply a bead of waterproof caulk, using a narrow rip opening to force it into the crack. Smooth it and remove the tape.

I thought TV space too, but don't see an electric receptacle there. Is there one in that space? If not, I'd get an electrician to install a receptacle there (shouldn't be a difficult job), and put a TV there.

This is a lovely room! In a small space continuity is important. Before you add or paint anything else, paint the daybed and both chairs a dark brown, British Colonial as mentioned above. This way you can add the color you want here and there. The table in front of the daybed needs to be higher, like a tea table height. Use the chest on the side. To make the daybed more comfy, add old fashioned wedge pillows across the back and then the big pillows on top. They are the best support and you won't even see them. https://www.amazon.com/Bolster-Replacement-Insert-Cushion-Perfect/dp/B011CZWYT6/ref=sr_1_3?ie=UTF8&qid=1542001435&sr=8-3&keywords=wedge+daybed+pillow&dpID=41J6VtPqM6L&preST=SY300_QL70&dpSrc=srch

move the wedding photo to the niche (or in another room). you actually need two of them (the one you have is hung too high) here's an example. or, if you want the one, try staging it like this. maybe tile the back wall inside the nice, try a wallpaper, a darker paint color. I've always liked this wall niche. I love the black/white inlay bone mirror. in this tall rectangle, it lookds great inside the arched niche. consider cutting a piece of wood for the bottom portion tried to photoshop it but your photo is crooked. if you could get me a shot of it standing straight on, I could play around w/it. beneath the mirror I'd place a piece of wood for the bottom 'shelf'. it would be like a sill. the wood would match your post or your flooring. you could do a small grouping of plants, or something similar to sit on the wood 'sill' beneath the mirror. now, for your entry table, do it like this. the mercury glass lamps/black shade, and the bright green/white floral arrangement is so pretty. especially if you do the black/white bone inlay mirrorr what about this version w/the art? you'd have to pick something you like, but fit it between two lamps, or some greenery and a vase. I like the ceramica stools beneath them. black would also work I actually have this light for my hallway. Bergamot 17" I also love a good piece of art. your table, a few key pieces If doing a mirror, do something in the right size, balanced w/other items. get some little ottomans to slide under the console, or something like these baskets these are three diff ways to style slim consoles. it's paired here w/a snow leopard rug. but look at the top left.. the white vase w/plant leaves, stool/basket beneath, a little lamp, other elements and a large mirror. (I like a nice piece of art better) this is the size you'd want here's a large mirror, console, small stool to slide under it, and a nice potted orchid. and a cool light dont forget some cool lighting.
