Hello, We are upgrading a condo (it is rented out nightly) and need to do some updates. The carpet is a carmel (dark beige colour). The kitchen has white cabinets. We will be replacing the sofa/chair, dining table/chairs, new countertops and tiles. For the kitchen was thinking to do slate (dark grey tiles). The backsplash is mostly white with a decorative bit that goes horizontal in yellow flowers. Thinking to replace the decorative bit with glass tiles in black/dark grey/light grey. Does this work?? And what color sofa a paint for the walls. Everything needs to long wearing colours that don't show dirt too easily. Thanks !!
