It's cheap. That's why you're considering it. Make sure that you note that there is no hot water in the showers. That's pretty common in El Nido for the cheap places, and it says so on the site, but don't miss that. The wifi is... Well, it's rough all over the island, but be forewarned. Finally, there're brown outs. We had an AC room, but when there is a brown out, it's fans only. That's not such a big deal. It's cool enough at night, but the generator was behind our room, and the sound of it going on or off at random hours made it hard to sleep.
It's a little down the road from the main drag. That's not a big problem, but it does mean you're not on the beach or at the downtown area. Still, it's cheap. The service is fine. Really, for what you are paying it's totally fine.
