Q: we are a group of around 9-10 persons (4 children) and we need accomodation for 3-4 days. we are interested in low cost options and also considering sharing of apartments.
A: Sorry dude, there is no cheap accomodation in Abu Dhabi. The only thing you can do it to check out if anybody (what I doubt) will rent out their villa while they are outside the country. These people would offer their accomodation in the daily like Gulf News and Khaleej Times. But for 3-4 days only? Both papers you can read online. Btw: Please note, that it's forbidden to sublet an apartment for commerical use on a short term. All the best!
