We came to Luz en el Cielo seeing it had fantastic reviews on Tripadvisor, but for us it didn't live up to its reputation. Don't get me wrong, it has great potential! There are just some basic things that need a bit of work.
Kiwidiwi's review (below) is spot on, but I would argue you won't find a place in Montezuma without noise at night - street noise, beach noise, drum circles. It's part of being in Montezuma; it may be a small town, but it's bustling.
What I would add is that there are no lockers in Luz en el Cielo (or if there are, we weren't told about them), which is why I didn't give this place an "average" rating. The lack of lockers felt like an enormous oversight on behalf of the owners.
Like I said, though, the place has potential. The staff is very friendly and helpful, the bunks and common rooms are clean (though some of the guests certainly were not), and I liked the laid-back vibe.
