Take care that you have enough Pesos in cash with you, as the next ATM is far, far away.
Reception should take care to have enough drinkable beer in the fridge (not only Aguila light) ;-)
Although we found very friedly and helpful staff all over Colombia, at Los Angeles they were even a bit more pleasant and helpful! Location is great, in the middle of nowhere, with the ideal environment to spend some relaxing days (although European-minded people could get a bit bored after 3 days). Easy to reach Parque Tayrona, which in fact is more a tourist hot spot with swimming facilities, than a place to explore the nature (so better leave it out, if you want to see a nice rainforest)
