Tjaldsvæðið í Grindavík

auto-translated: Good site with enough pitches for tents and motorhomes. The sanitary facilities are in good condition. The kitchen and the lounge may not be entered with shoes, but that did not bother us. Only the sulfur smell gets annoying over time.
Would I come back? Yes.

auto-translated: We were there as a family and had everything we needed.
The children were able to use the large playground.

Use of the sanitary facilities, including hot showers, was free of charge. There was a large lounge with a kitchen.

auto-translated: We were there twice within 4 nights. During our first time there, the hygienic conditions were critical. But well - we came in the evening and they usually clean in the morning. When we returned two days later, there were the same original stains in the toilet area, the empty toilet rolls were piled up, the garbage was overflowing (the suitcases discarded by other campers were still there). Nothing happened there for three days. At least we didn't have to pay for the second night because no one was there in the afternoon, evening or morning.
The campsite has a cute playground for children and a large recreation room - it would definitely be something for families if the sanitary conditions weren't so catastrophic.
