Storage facilities are required for people moving out especially for people who move to Manhattan or Brooklyn due to the high costs of apartment space. To find good storage services you have to look through your options carefully. You are putting your valuables for some time in that place and also expect to find them in that condition when you return. You should go to various facilities and check them out yourself. There should be good security system installed in the facility because you would not want to leave your belongings in an unsecure place. You should have complete access to your belongings and should be able to access them at any time. Also make sure that the units are of the proper size so that they can meet unexpected needs in the future. You may want to add more items in with the old ones due to some changes in plan.
