The Hat was SO AMAZING. We absolutely loved staying here. We paid a bit extra for a private room with a private bathroom. Rooms were cleaned every day, and we had a lot of valuables in the room that we felt very safe leaving behind (there are lockers in the room that you should bring a lock for if you are the paranoid or extra-careful type[; ). We felt extremely safe and secure here, You must swipe your key to get into the building during the evening, there is an employee that stands guard by the entrance to the elevators, and you must have your key card to access your hallway and then to access your room. The rooftop bar is absolutely amazing and a great place to meet new friends. Breakfast was simple but delicious. Their tapas are delicious, the tinto verano was very good, and service was good as well. Rooms are airconditioned, View from our room (room 35) was great! it overlooked the street the Hat is on and we got the quaint little street look we want. The Hat is very close to everything you need. There is a market just next door, Plaza Mayor is a 2 minute walk, and Plaza del Sol is also a short (s not something the Hat can control, so you just need to know yourself and book according to your taste. I will 100% be staying here again when I visit Madrid.
