Allison's home might just become our home away from home (I'd by lying if I said I didn't check what home values were for it :P). We spent an amazing 4 day weekend there with our two dogs, as well as friends of ours and their toddler and dog. The space was more than spacious and we didn't even have to use the Finished-Room-Over-Garage! Our dogs loved the backyard area and we could confidently let them play back there knowing no breakouts or escapes were possible. The main living area was great for relaxing in the evenings or getting ready for the day's adventures in the morning, and while we didn't need a full kitchen (Asheville has too many amazing culinary options to spend time cooking my own food), it was great to have available if necessary.
The only con, and this is probably the most minor/pointless/petty con possible, is that it's not within walking distance of much. If you plan to spend time downtown or want to escape for the day, you will need to drive and park somewhere. However, it's Asheville, so everything was within a stones throw anyway and we were never too far away that a quick jet back home to freshen up, feed the pups, or let a kid take a nap wasn't possible.
We've already started planning another trip next year and will definitely be staying at Allison's wonderful home.
