Terrible hotel, they canceled our reservation with us in front because we do not accept that we will be charged twice the stay. We booked and paid for a room with 2 double beds for 2 adults + 2 children of 3 and 6 years, because the girl at the counter did not give us the room, she asked us to pay again and on top there were many homeless people in an inconvenient state entering the hotel to use the bathroom that is right next to the elevator for the rooms
