flooring choice over cement slab

[Steven Maduro]

Hello 

I am sure this has been asked and answered 

but each new year brings new products and therefore different considerations on an old question.

I am renovating the lower level of my house to feature an in-law suite

it is a ground floor apartment with adequate runoff so flooding is not a big concern

The problem i am having is coming up with the best flooring choice which will give me all my wants.

ultimately the place is a one bedroom apt 

where the living room and kitchen will share the same 14.5x14.5 space

small yes but the bedroom is 9.5x21 so it makes up for the crampiness of the living roomkitchen

I would like the whole place to feature the same flooring which is why I am leaning to vinyl plank but the good stuff which is pretty pricey. 

but it will allow me to cover the kitchen and bath area along with all the other spaces foyer, bedroom. laundry and living room. 

laminate will allow me to do the place much cheaper as I can find phenomenal deals on laminate, but I would need to go with tile in the bathroom at least which is not a deal breaker 

it just makes the place lose that cohesive look.

porcelain tile is about the same cost and more labor intensive but I only have about 600 sqft to cover

The sub floor is cement. so 

i will have to factor in underlayment for my laminate.

just wondering what some of you would do if you were in this same scenario and why

I know only I can ultimately make the best decision for me 

but it would be helpful to hear others thoughts and experiences.
