I was a happy customer of the Extra Space Storage on West 142d St & Lenox until we moved into a larger apartment. It met all my criteria:
1. Near subway and bus line, so you can visit your stuff along the way to somewhere else and not pay a second fare;
2. Near a liquor store, for an endless supply of free, new clean boxes;
3. Near a goodwill, so I could drop off stuff I didn’t want anymore without having to cab it or drive it away.
It was my practice while the stuff was in the storage locker to keep going through it and combining contents of boxes into new boxes and getting rid of things I certainly didn’t want any more.
