Subletting advice

Has anyone subletted their apt with Copley Group? I know all leases in Boston have that clause about no subletting but landlords are normally pretty okay with it as long as rent is being paid–just a little different now because I’m with a management group.

Should I tell management I’m subletting? I want to avoid any penalties or be hush hush if I’m not suppose it sublet.

Ideally I would have my sublets name on the lease so she can access the building, put her name on proof of residency files, etc. but does that mean I would be transferring my lease and therefore paying the penalty?
