Wife and I stayed for 4 nights with 4 children. There was plenty of space to spread out into 2 rooms (one with queen bed, one without), and the master is still private on the other side of the house. Here's a list of pros and cons:
Pros: Great location in West Asheville. Lots of cool restaurants, shops, grocery stores and breweries 5 min away. About 15 minutes to cultural downtown, the Biltmore or the Blue Ridge Parkway. About an hour to all of the outdoorsie sites (sliding rock, Mt. Mitchell, canverns), value, huge shower in master, the bed/pillows seemed to fine to us, Wifi worked, decent view of the mountains from balcony. Air mattress available. House was super clean and decorated perfectly. Washer and dryer.
Cons: Guest bathroom lacks counter space, balconies lack furniture (in addition to exposed nails on shifting deck boards), bring additional towels/sheets/toilet paper, paper towels, soap. There is some, but nothing on standby if you run out. No blue ray/dvd or streaming device (bring your own). Couch needs replaced. It's on the 3rd floor, but you should know that by now. Master bed on street side, but it gets pretty quiet at night and didn't seem to bother us. Ice maker not working, buy ice.
Bottomline, don't let the cons sway you. It's a great location at a great value. I mean, we did it with 4 young children. We would not only go back, but would recommend to friends.
