Will A rated sponsor COS include accommodation ?

Dear all

My sponsor is a A rated sponsor and He opted for maintenance certification as YES in my COS. which is

Tick to confirm the sponsor certifies maintenance for the migrant: Y

Will the above includes an evidence that my sponsor is willing to provide accommodation?

In a separate letter my sponsor also stated that the EXPENSES for accommodation and maintenance will be covered. But did not mention that they have provided ACCOMMODATION.

Is my maintenance criteria fulfilled ? please comment
