Really good deal for a combination of business and vacation. Discovered we were right next to the Regina Sofia Gallery so perfect for some cultural activities and the city centre is only 30 minutes away. Worth the upgrade to a superior room since you have more space and a great bathroom.

Cannot thank the staff here enough for their service. Our room A/C was running warm when we came in - they fixed it AND offered to move us to another room away from the sun just in case (A/C was fine after that). We asked about Wi-Fi - without us mentioning our member status, they said members get free Wi-Fi... More

2 excellent rooms for 3 adults: an overnight mid-April + 4 nights early May, made even a better value by nephew's government rates that included VERY complete breakfasts - otherwise E15.5 each! By far the best experience were front desk staff members Rocio and Julio. Each -- on multiple occasions -- assisted this special needs traveler with attentive, personalized 'above-and-beyond'...

I am a Marriott platinum member. This hotel did not treat us well and refused to provide free breakfast to Marriott elite members. The hotel was so noisy that I had to sleep with earplugs inside of my noise canceling headphones. We complained and they moved us to a different room, which was just as bad. I believe the hotel...

The reviews of this hotel are relatively spot on. The reception staff are not great, they're very slow, slightly lacking in manners etc but overall I spent around 15 minutes checking in/checking out so didn't experience any major issues there. The building is nice, with a large lounge area where guests can use WI-FI, i didn't use this though. The... More

This hotel was amazing! Such an excellent location. Close to public transport, tourist bus, train station and museums such as prado. The staff were so lovely and friendly. Only downside was that it was about 17 euros to have wifi in your room so that was frustrating but great connection in the lobby. Would definitely stay here again.

Amazing hotel with a lovely complimentary, mini bar, spectacular bathroom, and spacious rooms for Europe. The staff were kind and very helpful and it is located a block or two from the Reina Sofia museum. I loved everything about this hotel and would not hesitate to stay there again! Book a room you won't regret it!

We stayed at the AC Carlton for four nights ending 5/7. We were updated to a corner suite that was terrific. The hotel tends to be a little noisy because of the center courtyard design and the amount of wood. The front desk manager Julio was fantastic. He was very helpful with several issues about the room and made great... More

Madrid was the last leg in our 2 week European Odysee. It was also my favorite leg of the trip, hotel not withstanding. We booked this hotel, because our travel companion's mother is a Marriott employee. I love Marriott, but this hotel definitely did not meet my usual Marriott standards. Location is decent, but not great. Walk able to metro... More
