Condos tend to be better maintained and are often built a bit nicer than buildings built for rental purposes.
As a rental apartment is maintained by the landlord, the public spaces of the building tend to get minimal attention... But with a condo, the entire building is maintained by the residents, so the public areas tend to be given a lot more effort. The people who actually take care of the building *live* there rather than come by every once in a while. When something breaks, it is usually fixed very quickly... With rentals, unless it`s vital, it may not be fixed at all (it`s up to the landlord.)

Otherwise, they basically are the same thing. A building that has multiple units with a different family living in each one. The biggest difference is that in one, you pay by the length of time you live there and nothing is yours - and the other, you own everything inside the structural walls of your part, a percentage of the structure itself and a percentage of the land.
