We used Jacotrans last May-June and they were very reliable for every kind of place we stayed.
I used Jacotrans 5/2017. It helped solve an incident because of my own mistake.
The story is:
I stayed in an albergue which did not accept "luggage transfer". As such, backpacks were placed in a cafe nearby to be picked up, and I was required to place my backpack in the cafe to be picked up the next morning.
Next morning, when I arrived at the cafe, I saw many backpacks close to a table, I "assumed" those backpacks were to be picked up by luggage transfer service, then left my backpack there.
I then proceeded to the intended albergue, but my backpack was not there.
The "receptionist" of that albergue was extremely helpful. He called Jacotrans, Jacotrans went back to the cafe, found my backpack and delivered it to the albergue within a hour after I reported the incident.
I would like to take this opportunity to express my appreciation of Jacotrans' service, the kind receptionist.
A lesson learned: the backpacks mentioned above were belonging to a group of pilgrims who were enjoying their morning coffee. There was a specific location in the cafe for backpack pick-up in any cafe serving such drop-off.
