Hostels in Guanajuato State, Mexico

Single room is not cheap but there is a big stone pillar in the middle? The room can only use WiFi. The 2 phone cards you bought will not receive the signal. The door in the room may be locked from the outside and cannot be opened from the inside. There is another iron door in the room leading to the outside alley that is also locked, for fear of escape doubts. The door might be accidentally locked from outside.People cannot open the door from inside which caused my security concern.
