We stayed at the Hotel Atlantico for 3 nights in December. Definitely a great spot. Super convenient location, walkable to all of the amazing sights in Madrid.
Our group got two rooms -- both very spacious. Desk, small table, end tables, HUGE closet. The bathroom was also big, and sparkling clean.
I loved the breakfast buffet -- very affordable for 12€ per person. A great selection of eggs, meats, cheeses, breads, pastries and fruits. Also coffee and tea. The lounge on the 9th floor was also amazing! Definitely check out Gran Via from up high.
The staff is good, not overly solicitous. Our rooms were ready when we checked in post-red eye which was a dream.
I knocked a star off because the walls are thin and you can hear loud folks from neighboring rooms, the hallways and upstairs. If you are a light sleeper, this may be bothersome. Also, our rooms faced a small dark courtyard, so not much in the way of natural light.
Regardless, I definitely recommend if you are in Madrid!
