I have friends visiting in Sydney in July and I was wondering if the Waldorf Serviced Apartments in Eastwood would be a good choice for them to stay. We live in the next suburb and it would be convenient for us to pick them up and show them around, but I am not sure about the noise. It seems it is next to the railway, and I am not sure if the noise level would allow the guests to sleep. Are you able to advise??
