Dear Guest
We change sheets for EVERY NEW GUEST as a regular procedure. And we change them every other day if you stay longer than 2 days. We have our own laudry service and procedures for quality control.
I don´t doubt about you being bite, but you should be aware you and your couple visited some other cities and hotels before arriving, and bugs could have being brought by you in your luggage or clothe.
We have a special procedure for guests comming from Chivay and Puno, (rural areas). We can´t reject them but when they live, we check intenisvely all the room and covers, and if we suspect about them infecting any of our rooms, we fumigate it imediately.
A World Mining Convention has being held in Arequipa Set 15-20, and we were selected as an official Hotel for the event. As part of the requirements, authorities supervised EVERY ONE of our rooms (including 116, where you stayed) a week before that date. We did not receive any negative report. No bugs.
Sorry for the inconvinience, but I can answer firmly, those bites were not caused by anything located in the room before your arrival.
