I'm sorry for your loss. It's always hard trying to rethink yourself after someone important is no longer spending your waking moments with you.

The hallway is very narrow. It's how you and your guests enter and leave the apartment. It should have some enjoyment for you as you walk past the area. Large, nicely framed, vintage poster maps of places you have been would work here.

Interspersed between the maps you can put artifacts from your trips or something significant as a wall hanging by the poster.

In effect you create a memory wall of all your favorite places that you have been to or plan to go to. Add a nice rug runner to compliment the color tones in the images.

Great ideas, I guess my other pics were not loaded so you could get a better idea. My style is contemporary and sleek even though it does not show in pic.

Please keep them coming.

Optionally you can hang a series of mirrors that would serve to brighten and visually enlarge the hallway.

I'm sorry for your loss.

That's a very narrow hallway so be careful of putting too many things on the walls that might get bumped by shoulders or swinging grocery bags. How about doing something really special with the inside of the door? (Not necessarily this, but here it is for inspiration.)

My front door is metal, and for now I have a very large photo held onto it with magnets. The photo contains a quote that I find uplifting and it's nice to see it on my way out to the world each day.

What a wonderful idea lucidos has for creating a colorful poster/map "memory wall" of places you and your husband shared. Her examples are beautiful. Leave space for new places you may visit! Since your apartment is small, keep the paint color throughout the same, but use art work, pillows, curtains, and rugs for your color instead of an accent wall color that might darken the space. If you're allowed, you could paint the interior doors.

Some thoughts about laying out your space:

--Float your sofa so that it faces the fireplace wall. Overlay a colorful rug that will define that space. Make sure it's big enough so that the sofa and facing chair touch it. Bring in your coffee table and maybe get an armless chair for the corner near the fireplace. Keep them within about 20" of the coffee table so you get a conversational effect.

--Move your existing easy chair to the left of the fireplace so that it faces your TV.

--You might want to think about getting a much wider low media stand with several shelves. Your current one is bulky and take sup an awful lot of real estate. Ikea is a great place for open, modern media shelving. Then you can arrange your decorative items, art work, and TV along the top.

--If you get a new rug, change out your curtains with a color from the rug or some of your art. Ditto on new sofa pillows.

I'm sorry for your loss. It must be so disorienting to deal with many reminders of your husband. Take your time. If you're in doubt about keeping or downsizing some things, photograph them and make a memory book. Memories are what count, not the objects themselves. Much luck!

I am so sorry to hear about your loss, and would like to offer a few suggestions to help your new apartment welcome you home.

Consider a tone on tone effect for that wall. Done in high gloss, it will reflect light , and transition gently into the living space. I would carry it over the door, and behind the fireplace. Painting out the doors and door trim on the opposite hall wall will streamline things more. Budget permitting, look at replacing the hallway overhead with a chandelier, and adding a small lucite shelf below the mirror on that opposite wall. I find scent to be both uplifting and comforting, and would add a candle to the shelf's items - a good quality one ( Scentsational, Nest) can be used unlit. The larger the pattern on your walls, the sleeker the statement ( and stripes are simplest of all).

The mirror appears to be reflecting the TV. If so, a larger piece of artwork would be a nicer replacement. If a mirror is preferred, look for a black frame ( or whatever shade the dark drape is) so that it becomes more of a statement.

Given your preference toward sleek decor, I also suggest removing some items -leaving one pillow on the armchair, one plate under the TV, moving the candleholders from the Naguchi to the fireplace, placing all the tealight holders together in a single display somewhere , and stacking the prints by the TV vertically on a wall - perhaps that becomes your fireplace art, or moves to the kitchen/dining wall. Remove all the dining table bits but the bowl, and add some texture to it - I'd probably go faux artichokes, as they are visually strong, and easy to find (Target, Bed, Beth&, etc.) Again, a chandelier over the table can relegate the landlord's choice to the closet.

On the coffee table, since you have so many bowls, why not try something different and look for a beautiful box to hold your remotes, etc.

Finally, and again if budget permits, I think a new wall colour all together would go far in making this your own.

I wish you all the best as you start your new normal.

So many great suggestion, studio 10001, is in my zone. Lucidos too.
