Maria's place is an awesome bargain aparthotel, just a few blocks from the Obelisk, in an older building, so not at all fancy, but clean, and with daily maid service and 24 hour conserje and top notch security. Great hot water, great AC, really friendly and helpful staff, and checkin was a breeze as there is a dedicated recepción desk. I LOVE these guys, as I foolishly left my camera in the lobby as I was getting ready to head to the airport. I was already there when I realized, but a desperate call to Maria revealed that Guillermo the head conserje saw it and saved it for me! After that scare, Maria went way, way above and beyond to arrange to ship it to me! Super cool, super sweet people! Will return!
