I like black, but not for the walls. It's too dark, especially if you don't have something to counter it. Normally, you would get lighter accents with a black background to disrupt the continuity and make the room look larger. I think its the current trend now to have this. Not a big fan if they are going to do the same treatment for all of the hallways. I wished the builder spent the money on the workmanship in the units than having black marble in the hallways.
As for the heels, it doesn't matter if the person is large or not. It depends on the heels. Ever hear stilettos hitting the floor at 2 am in the morning after the Caribbean Festival, where the person decides not to take off them and walks for 15 min around the room. Not fun at all.
