Hotel JW Marriott

We have recently completed the low-voltage and special electrical installations of the new 5* JW Marriott Madrid hotel, in the heart of the capital (C/Sevilla, 2) very close to Puerta del Sol and Paseo del Prado. The hotel has 139 rooms spread over 7 floors, some with impressive views of the city. Inside we find the new restaurant Qú by chef Mario Sandoval, winner of two Michelin stars. We want to thank the Millenium Group and the San José construction company for the trust placed in us
