Is it correct to say: "Problems that face them"? Thanks in advance

Lleida Lleida is a city which is located in the west area of Catalonia. It has a hill where in the past people used to control all the Segrià region. It has as well a river that provided water to the city. On top of the hill there is Castle which was constructed by Pere de Coma. Lleida has a lot of natural spaces, the river, la Mitjana, parks where children can play… It’s a nice place to live.
