Kitchen area:

--In such tiny kitchens, open shelves make sense as long as you make a commitment to being very neat about them. Why do you have cabinets in front of the window? You could do a smaller version of this to let in light:

Consider having a small, not-too-deep bookcase built with marble top against side of stove. Use for your cookbooks and a small landing spot next to stove. It can't be too deep since bathroom is there--very weird location for a bathroom. Do you have a garage on the other side of left door as you face kitchen? If so, and there's room, put tall steel shelves for your baking pans, etc.

Island and dining space:

--Consider an island with corner angles for ease of passage and possibly a demi-lune dining table on the other side of the island. Your current dining area is too small for full-four sided dining table, but a table extension or banquette might be great solutions.

Banquette seating and table against dining area side of island. Flip-up seating under cushions would give you storage for large cookware.

Other possibility is to turn the "nook" area near the stairs into a dining nook with a small round dining table and chairs--could be banquette like this or just round table a few chairs with a great pendant dropped over it to set it off. Using that stairway space for dining would leave you room for your island. But do be very careful about the size so it doesn't overwhelm the space. You need plenty of space all around the island.

Start doing a search for "tiny kitchens" to see what possibilities are--open shelves; spaces outside kitchen; use of stairway nook. You need to see the space differently than you do. Never block light coming into a kitchen.
