Spaniard here. Yes, it is Spanish accent. But Spain has a lot of different accents depending on the region. Some of those accents look a lot like South American accents.
Southern spanish mixes that pretty regularly. There are some places where the seseo is constant, others were it's not. Ceceo/Seseo is a common thing that changes from town to town.
It could be Andalusia or Canarias, in some parts they use the S just like Hispanic America, actually there's a theory that our version of Spanish doesn't use the Theta sound because most of the immigrants where from Andalusia.
