Stayed at ATM because my first choice (our melting pot) was booked.
Dorms are kept clean and a towel is provided. A filling breakfast is included on the price and served on the roof terrace.
Didn't strike me as the most sociable hostel (there's the roof terrace as a common area but I didn't notice anyone using it) but I met some great people in the dorm.
Location is right in the centre, managed to stagger home from Pukka bar a few times!
Booked tour A and tour B through the hostel for only 1000 pesos each which I believe is cheaper than most other places. The tours were high quality and guides were really good. Staff are helpful and you can book almost everything through them.
I would advise booking before you arrive as El Nido gets really busy and I met quite a few travellers who traipsed round numerous hostels before finding a bed!
Tip: avoid the bed right in front of the aircon as I was freezing the first night but managed to move beds the second!More
