My experience in the brand new Nido Hotel was extremely awful!!! The AC unit in my room was extremely underpowered. I arrived very early in Madrid, but my room was ready at 3pm (that's not a negative on the hotel) but when I opened the door it was literally a steam room 29 Celcius (84F), we turned on the AC at the highest level and at 6pm the room was 28 C (82.4F). We called the front desk and they sent the ac technician, he was a very nice guy and basically he said that the air was coming out cold, but he basically said that it was going to take many many hours to get to 22C, but he knew that it was not happening because they have them all set up to be extremely efficient. At 11pm we simply couldn't handle the heat and we had to find and pay for a different hotel. We went downstairs to explain again, but basically he said that he was going to let the technician know to see if they can set them up a little bit better for the next few days. We found a hotel 11:30pm (literally a few steps away)and we took the chance, thinking that it was going to be the same, but to our surprise in only 30 minutes our new room on this new hotel was already feeling better, around 2am the room was nice and we finally had the opportunity to have a good resting sleep. Stay away from this place! To our surprised, we learned that this is a brand new building. Also, there is not even 1 ice machine in the whole building, the room has a full kitchen without a single cup, plate, etc.Horrible experience!
