When you say "nothing" are you setting up house keeping from scratch?

Welcome! I wish you much joy and laughter in your new home and here in the US!

i would try IKEA if you have one anywhere near you. You can get everything you need there from dishes to furniture. For starting out, I think that is a wonderful resource. If there is not a store nearby, try online. The other online stores mentioned are good as well. Please come back with pictures of the finished space!

Welcome! What an adventure : ) .

Many stores in the US, both online and "brick and mortar", have very good return policies and also free return shipping, so check to make sure before you buy something that you can return it if it's not a good fit, in terms of size or style. Also, for online shopping, stores have frequent sales, especially around US holidays, and you can also get emails with information about discounts, so it's worth signing up (perhaps with a different email) for some of the companies that you like.

Ikea has good and inexpensive housewares, in terms of pots and pans, dishes, etc.

Pottery Barn, which has stores and is also online, has a new line of smaller furniture intended for apartments. This might be a possibility for you. Here are their small space sofas,

and here is their new PB Apartment line,

Other online companies with more modern furnishings include CB2 and West Elm.

Are you in the US temporarily or semi-permanently or permanently? That might affect how you go about purchasing and decorating.

In addition to the things already mentioned, if you have a Macy's with a furniture department where you are, they have brought in some new things recently. We went shopping for my son's first unfurnished apartment and found some reasonably priced sofas and chairs, especially when on sale. They had both fabric (mostly grey and beige) and leather (beige, brown, navy, ivory and even peacock blue, apple green and terra cotta). And they weren't all puffy marshmallow man sofas.

I have also seen some great outlet/clearance items online at Joss & Main, but you can't try them before you buy. And it's hit and miss with what they have at the time you are looking. I had seen some things I liked earlier, but nothing when my son needed furniture.

I would like the idea of introducing some blue and/or green to tie in with the outdoors. It doesn't have to be anything as large as a sofa, but it could be.

Have you checked out Target? They're having an online only Home Sale right now (20% off). I'm not in the States so can't comment on their quality but I browse their furniture often and find it quite affordable and it often looks small-space friendly.

Best wishes and good luck!

Sounds promising. I would include some of the blue either in the throw, or in a pillow (gray and blue) for the loveseat.

I hope the apartment, and your city, are starting to feel more like home.

What else is in the room?

What isn't working about the current curtains? The fact that they're sheer? The color? The weight? What do you need/want curtains for? For privacy, or against glare, or to look pretty, or some combination of that?

I would decide on the rug first, and any other furniture you need, like a coffee table, and only then tackle curtains.

I think the curtains would work but you need them fuller....how about another pair on added to the window...that will make a great difference. You could look for colored sheers also.....either J. C. Penneys or Walmart has sheers.
