I spent four months at the Four Points earlier this year and the previous poster summarized it quite well. The hotel is ok, a bit dated, but works well. The staff are great.
The rooms are very much to my taste and even their smallest rooms are quite spacious. The food in the lounge is ok. The gym is small, but has the basics. The major downside really is the location as it is far away from anything in Riyadh.
The Aloft is now maked as opening in January 2016, so it really is taking its time...
