1. Manly Boardrider Hostel
Staying in a hostel is probably one of the best options for travellers whose a tight budget for your trip. In addition, backpackers accommodation is not only cheap but also a nice place to meet and socialize with people all around the world. However, I have seen many people are not comfortable with this type of accommodation because of many reasons. One of those would be they do not want to share the bathroom with others. In addition, due to it is a low budget accommodation, the room design and service is overall not as good as a hotel or even motel.
