I'm an American and just came across this thread, so hope I can help out. Basically the term 'condo' is a legal term which means a residence that a person owns, as opposed to an 'apt' which in the US means you're paying rent each month and have no equity in the property. Also, when owning a condo, you own the space inside and are responsible for that maintenance/upkeep yourself. However, items on the exterior (roof, external paint, windows, common area/landscape) are jointly owned by all members of that particular condo association. For example, your monthly mortgage payment might be $1,200 and you would also have a condo fee of maybe $300 per month.
Again, 'condo' legally has meaning for the owner, but as a rental vacation property, I imagine you don't really care what it's called, and are only concerned with the amenities. Unfortunately, 'condo' is a catch-all phrase much of the time. Beware that there's no 'exact' definition that states a condo must have....a pool, spa or whatever.
Always ask what amenities that particular condo has, and get this in writing. Price would vary based on location, amenities, age of building, etc. For example, renting a condo in the US would almost always mean having a dishwasher, washer, dryer (tumble dryer as you say), a/c, and fully-equipped kitchen, but make sure. Also, make sure it has a pool if that's important and find out what floor the particular condo you're renting is on. (Might be a high-rise which would almost certainly be required to have a lift..these are most likely in urban areas like Miami Beach, NYC, or Boston. Or it might be a 'garden' style..with one - 3 floors and no lift..most common around suburbs and the Orlando area and wouldn't have a lift...important if you had little ones in a pushchair or whatever...
Good luck
