I did want to write a review immediately after my departure one month ago. Now I am in Colombia and have been to 8-10 hostels in this country.
Guamnachi is still the best posada I have encountered during my travel in South America. Friendly and helpful staff.
One note: The TV room could have been arranged in a more comfy environment and a TV set is outdated.
Thanks and hope will lodge at Guamanchi again.
