Can't wait to come back! Miguel is super communicative and provided great suggestions to experiencing Tijuana, especially for NYE. The location is relatively isolated, but we took $2-6 uber rides everywhere. It was very safe, as was the premises (there's a 24 hour security guard). Currently, if you cross the border on foot, you come down on the San Ysidro trolley station side (~10 minute walk from the crossing to the Estacion Federal), and you can leave the country using the PedWest Border Crossing.
A lot of things were closed because of New Years, so just something to keep in mind if you plan on visiting during public holidays.
