A characteristic (in general) of all the hound breeds is they don't have the innate desire to please their owner, as opposed to say, Labrador Retrievers.
At the same time, that trait makes separation-anxiety much less of an issue -- a real plus if the dog has to spend a lot of time alone.
With bassets, housebreaking can be problematic.
Another variety of dogs that are surprising couch-potatos and can do well in apartments is greyhounds. A lot of them are content to sleep about 23 hours a day - not a bad life
