With the right kind of bun, ketchup and mustard, wiener dogs are great.
I say ketchup on a hot dog is an abomination! ;-)
But we love our dachshund mini, "Kitty"! My family had dachshunds when I was growing up, so I'm familiar with their temperament, health issues and suitability as house pets.
Kitty at three months -- the size of a slipper.
Kitty at eight months -- nearly full-grown now.
Like most miniature breeds, dachshund minis are more active, some might even say high-strung or nervous. They do tend to bark a lot, but can be trained to reduce that behavior somewhat if it's undesirable. They can be very destructive (chewing) if bored, so keep in mind they either need a lot of interaction, watching, or to be kennel-trained for times they're left alone.
While it is not uncommon for them to have back issues, they can also have "normal" dog life expectancies if they are well cared for, and restricted from jumping up or down from high places. It's difficult to curb their enthusiasm though.
Any web site catering to common dog breeds can give provide a wealth of information on dachshunds, and the assumption is likely that minis are now probably more common that standard size.
Don't hesitate to ask more specific questions if you have them, and good luck with your decision.
