Casa Tranquila is the nursing home and assisted living facility in Albuquerque, New Mexico, where Hector "Tio" Salamanca lived after his nephew Tuco Salamanca was killed. It was the location of the bombing that killed Gustavo Fring, Hector Salamanca, and Tyrus Kitt.
Gus frequently visited Hector in the facility to taunt him about his revenge on the cartel.
Late in the final episode of Season 4 "Face Off", Gus approaches Casa Tranquila with the purpose of exacting final revenge on Hector Salamanca, for his recent meeting at the DEA office. Unbeknownst to him, Walter White had coordinated a separate plan to take down Gus which resulted in Tyrus Kitt's, Hector's, and Gus's death.
Casa Tranquila is featured on the DEA evidence board. On the board, the DEA has written that the "blast radius suggests an improvised device at the center of the room, most likely equidistant from the three people inside" and that "Ballistics indicate the device was attached to Hector Salamanca's wheelchair."
- "Casa Tranquila" in Spanish translates to "Home of Tranquility". This is fitting for the not-so-tranquil ending of "Face Off".
- Casa Tranquila is also seen in Better Call Saul, in the episode Alpine Shepherd Boy.
