This room, made by KAWAI, a well-known manufacturer of musical instruments, offers excellent soundproofing. It hasn't been used much, so it's in relatively good condition. It has a ventilation fan, allowing for proper air exchange. Since barking sounds are almost completely contained, you won't have to worry about disturbing your neighbors. This is a useful item.
