Close to airport but far from the city. However it is cheaper to go to city centre than to airport through uber (depending on time of course). Hotel is quite luxurious and have great friendly staff. Good selection of items for breakfast.
Overall the room and experience was pretty good - big room, with washing machine, microwave and various other things. There wasn't much service, but I want really looking for any, just a place to stay. There wasn't much in the immediate area, but it seems you need to drive/everywhere in Riyadh anyways, so it's pretty centrally located thinking about that. A weird smell initially in the bathroom upon arrival, but that seemed to dissipate... Overall a pretty good option if you get a good deal!
Given how expansive Riyadh is, this hostel is in a good location and helpful instructions were provided via WhatsApp prior to arrival. Others staying at Su Casa were people living and working in the city, but there were small and meaningful opportunities to meet others over coffee and discussion. The bed was comfortable and the amenities basic but more than sufficient. I did not love Riyadh as a city personally but I certainly felt at home and like nothing was a worry. For anyone arriving via public transport, buses accept Visa and Mastercard and it is possible to connect nearby (~10 min walk) to buses, although expect to face traffic depending on the time of day.
