You may deduct real estate taxes you pay on real property that you own. If you don't own the land, you can't deduct property taxes even if they are included in the lease.
You can deduct mortgage interest you pay on your main residence and one second home, such as a vacation home. However, that would not apply since this is a lease.
There are no other tax breaks I can think of for a personal vacation property. Personal expenses are almost never deductible, except for certain expense for items favored by Congress (like benefits for owning a home or donating to charity.)
