Las Galeras is a fantastic place for travelers to enjoy their holidays. If you are traveling on a low budget you should check out the Ballena backpacker hostel. It is located only about 200m away from the shore.
You can choose between matrimonial rooms with a private bathroom or a dorm with shared bathrooms. The internet connection is stable and fast. All beds are with mosquito net and fans are provided as well. The windows to your matrimonial rooms also have mosquito nets.
The owners Barbara and Franco speak English, Spanish, French and Italian so you probably will have a common language to interact with. They also run a Haitian arts gift shop very close to the hostel which you should check out.
