Only having spent one night here and it being my first experience of 'camping' in North America, I can only compare to the many European campsites I have stayed at.
Firstly, Yosemite is an absolutely stunning place and I cannot think of anywhere better to be under canvas.
Staff at check-in were curteous and thorough.
We easily found our 'tent'; which is actually concrete walls on three sides and a canvas front, with a walled in seating area and a fire-pit.
The tents have a double bed and bunk beds with a metal shelving unit and a pole for hanging clothes from; as well as a fixed electric light inside and out, and socket for charging etc.
Also there is a picnic bench and bear-proof food locker (which MUST be used to store all items of food, drink and toiletries to prevent nosey bears from entering your tent area or car! We also placed everything into airtight Ziploc bags)
Toilet blocks were clean and close by, however the single shower block did get busy very early on.
In comparison to European sites costing a similar amount for fixed camping, this is very far behind on the standard of equipment and services provided; which are basic.
You do get the feeling that because they have the monopoly on this area it is very much take it or leave it. I am aware that being a national park they wish to keep it as untouched as possible, but it is expensive for what's provided.
That said, the setting is fabulous; tranquil and beautiful. Also met several interesting people on our short stay as we star gazed on the bridge. Fortunately, no bears.
One thing which was surprising was that with all the ongoing concern about the Hansa virus outbreak including being handed out information leaflets on arrival, the tents themselves were not clean at all. All surfaces were covered in dirt and dust an appeared not to have been wiped down for some time.
