Can I repaint the walls or change the curtains?

Generally, no, but there are rare exceptions.  Usually building managers paint all the units in the same white or off-white color to make it easier when they have to repaint between tenants.  But some high-end units will offer a custom package for color changes – at an extra cost.  You may be required to change them back to plain white at move-out.  Same thing for curtains – they do frown on you changing them.  If you do make a change, you’ll need to put the existing ones in storage and replace them when you move out.
