I used MM Packing and Storage Service for 2 years while I was in US, it was very cleanly maintained and none of my household items were damaged. Initially they showed me their warehouse and I was surprised to see how compact they stored all the stuff.
They also perform pest control for all the warehouses and that smell would stay if you are planning to keep your old clothes.If you are keeping your old clothes please use solid suitcases so that the clothes does not damage. Furniture and other household items can be just stored as is.
They also store mattress with full care which was quite impressive. Totally I would suggest MM Movers if you are looking for best service and best price.
