No, if you decide to do all the relocation process by yourself, this will not be a smart plan even though you do domestic relocation. Even if you are new to Mumbai, it will be a tough one. It will give you mental as well as physical stress to pack all of your stuff into cartons and move them to a new location.
You can avoid those stress when you get the assistance of a qualified moving service who can provide moving support in the crowded city.
