Hello,
You can book in to the Villa Moda Hotel it is in Al Saad near the Lulu. They charge 6000 for long term rent. I stayed there for 6 months and it was good. You have a gym, free internet and all the rooms get cleaned every day. It is only a hotel room and it only has a small fridge. The larger rooms with a kitchen cost more money. I would suggest booking the room on a single occupancy bases to get the best rate and nobody will bother you after that. Call 444215424
