We stayed at this Hosteria in December 2011, family of 5. La Merced del Alto was our first choice but was fully booked so we went to this hotel which was recommended to us. Out of all the hotels that we stayed during our trip to Salta, Jujuy and Tucumán, this was by far the worst and the one I would not stay at again. Rooms and bathrooms are clean, hot water available, breakfast included, so if it happens that you NEED to stay here, you'll be ok... I am just recommending you try other places first. Specially because it ended up being one of the most expensive hotels because we are not ACA members! (20% discount for members makes it a more reasonable option to them) Non ACA members - look elsewhere!
Good thing about this hotel is it is located a few blocks from the center square of Cachi and everyone knows its location, so it is easy to get there, specially if you'll be arriving late.
