Stayed 2 nights at Hotel Ópera in Madrid. It is in a very convenient location near the Royal Palace of Madrid and Opera House, along with many other tourist attractions. The first night they gave us a bigger room (room 903) on the top floor. It had a great city view and palace view. However, this room had a broken air conditioning system. I ended up opening the casement windows on the slanted roof/wall to get cool air at night. Also the shower door was too wide it couldn't open all the way if swing inward or bump the toilet when swing outward. Otherwise this room would've been a cute room for kids with 3 beds. The staff was nice enough and relocate us to a different room on the second night with complimentary breakfast. The relocated room had no problem. Due to the location, you can hear the street and crowd noise at night. It is one of the less expensive hotel around this area; but you get what you paid for.
