This refugio was by far the worst refugio on the W-Trek. We really can't recommend this one. First of all, when we arrived there was a storm coming up, it was very cold. The temperature in the refugio was 12degrees (many guests were complaining). They even didn't give out free hot whater when we asked for it.
Next, the bed which was given to me was full of hair of the previous guest and also selfmade earplugs (with toilet paper) from the previous guest.
We had great stayings in the other 2 refugios, but this one we can't recommend. We recommend to make the first or last night (depending on the direction you are going) in the refugio grey and skip this one.More
