Breach of Lease by Landlord?

Hello, me and my wife moved into a condo managed by a certain company. When we moved in they said that the hot tub was fully functional and never actually let us in to see it claiming they did not have a key. Then we moved in and we were told that the HOA division responsible for the building did not have the money to fix the hot tub and there was no date set in stone when it would be fixed. We recently saw an add by the same management company trying to lease another unit in the building saying there was a fully functioning hot tub. We printed it and kept a record of this. It has already been six months and the agent being the management company for the principle did not inform us of this while moving in. Can we technically sue for all of our money back that we have paid so far on the lease, aside from just breaking the lease scotch free, which I know we can do. How much would that cost and would it be worth it? Probably about 6,500 spent so far
