Not stayed in those apartments, but have been to Costa Teguise.
I liked Lanzarote a lot. There is lots to see and it is worth hiring a car or going on a couple of tours. BUT, I didn't like Costa Teguise. It is totally devoid of any character, full of English bars selling English beer and showing English football. We ate out a lot and while we didn't have a bad meal, none of the places we ate out in were that good either. I cook better meals at home.
The first time we went to Lanzarote we stayed in Puerto del Carmen and liked it a lot. But that was over 20 years ago and it is busier and brasher than it was.
