Our family have bought an dsold enough things on ebay to know that photographs make anything look biggers, cleaner, newer than it is in real life, to know that we would never choose a place to live based on pictures alone. I also wouldn't pay for a service looking for flats/rooms to rent when estate agents offer that for free. Possibly international students might, but, generally in the first year they are accomodates by the university and in subsequent years they would be in the country and available to look physically themselves.
