I´ve used this hotel for different friends before, all the time get the invoice (factura) was an issue, the accounting person was not there, people in the front desk dont know how to print the invoice, they were supposed to send it by mail... I had to call many times to get ir (sometimes I never got the thing).
However location is convinient and hotel is OK. Last month I booked it for a friend, I received the charge on my credit card and my friend was asked to pay there again, I contacted Expedia, They have been trying for a week to get an answer from the hotel... Never got it, so we paid 2 times for the same room. Bad experience.
