Flooring suggestion for uneven concrete floor
I'm beginning to remodel units in a small complex with concrete floors. Here is a before picture of one of the units. They all were kinda ugly and had rugs which would require constant cleaning or replacement:
Here is an after, with vinyl plank flooring:
It looks a lot better, but this particular unit had a pretty even floor. There are some that slope down a bit at one point, maybe where a wall used to be.
Any suggestions on durable, attractive, but not too expensive flooring? I've considered linoleum.
