The DappBnb project is a decentralized application built on the Ethereum blockchain. It is a rental marketplace where users can list, book, and review apartments. The project revolves around DappBnb.sol, a Solidity-written Ethereum smart contract. It leverages the OpenZeppelin library to ensure secure and standardized development of the contract.

The core of the contract is defined by three primary structures: ApartmentStruct, BookingStruct, and ReviewStruct, representing an apartment, a booking, and a review, respectively.

• createAppartment: Allows a user to create a new apartment listing.
• updateAppartment: Allows the apartment owner to update the details of an apartment.
• deleteAppartment: Allows the apartment owner to delete an apartment listing.
• getApartments: Allows a user to fetch all available apartments.
• getApartment: Allows a user to fetch the details of a specific apartment.
• bookApartment: Allows a user to book an apartment for specific dates.
• checkInApartment: Allows a tenant to check into an apartment and triggers the payment process.
• claimFunds: Allows the apartment owner to claim funds after a booking is completed.
• refundBooking: Allows a tenant to cancel a booking and get a refund.
• getUnavailableDates: Allows a user to fetch all booked dates for a specific apartment.
• getBookings: Allows a user to fetch all bookings for a specific apartment.
• getBooking: Allows a user to fetch the details of a specific booking.
• addReview: Allows a tenant to add a review for an apartment.
• getReviews: Allows a user to fetch all reviews for a specific apartment.
