Oobi, Uma, and Grampu originally were going to have a different apartment to rent while they were on their vacation, but a richer man bought their apartment, so they live in a slightly run-down apartment on the second floor. In Ox's Revenge of Another Oobi Vacation, Ox sends the gang to the same apartment in a bag.
The apartment is located in Abu Doobi, Oonited Arab Emirates, the main city in the series. It is consitered a run-down building to others, but it is fully functional to the people who live there. It has tile floors and sofas, with a television and kitchen. There is one bedroom which Oobi, Uma, Charlie, Dave, and Max share, and another where Grampu sleeps and Inka when she visits. In Oobi's room there is a TV, and there is a small laundry room next to Grampu's room. There is also a pool in the back which they share with all the other residents.
