For Madrid go to <a href="http://en.venere.com/hotels_madrid/" target="_blank">http://en.venere.com/hotels_madrid/</A>

I always stay at Aparthotel Muralto. Near everything and transportation is easy. I always use the bus in that area. Also the Hostal Americano, unexpensive, good neighborhood and walking distance to Puerta del Sol and Museo del Prado.

In Barcelona, I always stay Aparthotel Silber, next to the Fontana metro. Two stops away from La Rambla. Very secure.
