Question Best Site for Rental Homes in Edinburgh?

We're planning a trip to Edinburgh at the end of June and will be staying for five nights. For the first three nights, we're looking into renting a home or apartment instead of staying in a hotel. Does anyone have recommendations for the best sites to find rental homes in Edinburgh? We're looking for something reliable, with good reviews, and ideally, options that are centrally located or close to public transport. Any tips or experiences with specific sites would be super helpful!
