One of the 4 bedrooms was probably intended as Majlis.

I am guessing you are going to share this with other mates, right?
If you are all girls and busy at work, I think a 20 year old building will now demand plenty of maintenance, which means a lot of headaches!

Even if the location is right, you will probably be uncomfortable.

For 7,000 QR you can find a decent 3 bedroom apartment in some nice areas including Markhia, Medinat Khalifa, Al-Mansoura, Al-Muntazah and Bin Omran.
