I recommend Citimax spruce barsha, an excellent network triple with delicious and plentiful breakfasts (tasty, fresh), near the metro in the mall, at the end of the mall there is a bus station. From the windows of the hotel you can see both Sail and Burj Khalifa. They are taken to the Parus beach. The transport interchange is such that you can get to Marina beach by yourself by metro, some took a taxi, in the mall across the road there is a Corfur chain supermarket, many food courts. In short, if you wish, you can visit all the beaches on your own, as we are in Dubai. Also try tour buggy, very interesting. I liked it very much.
