Madrid: Aparthotel Plaza de España?

Has anyone stayed at the Aparthotel Plaza de España ? I was just informed that we will be staying there with my high school student group and I haven't heard of this place...any one know anything about it? I am hoping it is near the Gran Vía and not down the hill towards the Palacio Real.

This aparthotel is owned by the same company as Los Jeronimos aparthotel - their websites don't have a lot of information. I'm looking for any information regarding Los Jeronimos too, so maybe we can compare notes once we hear anything about these places.
