I arrived @Cozy Room during my first visit there and learned my booking had gone into the hotel's spam mail. Subsequently, there was no booking for me and no available rooms.
However, Cozy Room immediately made it right-within 15 minutes they Ubered me, at their expense, to another hotel not too far away. I was heading to Machu Picchu the next morning so I left my luggage at the new hotel to hold until my return. Upon my return, Cozy Room had picked up my luggage and they were waiting for me upon my return @ the hotel where I stayed a night before my return trip to Lima.
Overall, their service was awesome and they sure made up for the booking mishap.
