I don't have a map or a link, but the numbering system is pretty basic. The first digit indicates the floor. The second digit indicates whether it is "airport side" or "Maho Side" with a 1 indicating airport and a 2 for Maho. And the last two digits show how far from the lobby the unit is. So unit 3104 would be on the third floor, airport side, four units down from the lobby. And unit 2211 would be on the second floor, Maho side, eleven units down from the lobby. Hope this helps
