I personally love white sheer curtains, I think they are so nice and airy and let in a ton of natural light! But based on your preference on color and privacy, there are a ton of other options out there. I would for sure do floor to celling curtains assuming you can remove the ones in the picture (or just cover them up with a more solid fabric). You could get some inexpensive pipe from the hardware store in place of a curtain rod and paint it if its not a color you like. I also love the idea of a sitting area by the window like in one of these pictures below! If you already have a chair that could go there all you would need is a lamp and a side table/small bookshelf and you’re good to go! To get that hotel feel I think stick with mostly neutrals, then bring in a few pops of color through accessories and plants!
