This is a beautiful, comfortable apartment! Lots of light coming in from the floor-to-ceiling windows /balconies. The location is UNBEATABLE. It is literally within walking distance from almost everything there is to see in Madrid. It is just across the street from Plaza Mayor, close to several Metro stations, and in the heart of an area full of restaurants, bars, and stores. Taste Madrid's famous churros con chocolate just a couple of blocks away - open until midnight! There is a Carrefour Express market for all your basic needs (food, toiletries) one block from the apartment. We also walked to the museums (Del Prado, Thyssen, Reina Sofía, Sorolla) in 15-20 minutes.
The wifi is strong and reliable. The apartment has all the appliances you might need. The listing says that the hot water supply for showering is limited, yet we never had a problem. We were 5 adults, 3 of us showered in the mornings, and the remaining two at night - we all had enough hot water.
One of the bedrooms has no air conditioning, and the first night was too warm. Marcelo got us a new fan two days later, and that fixed the problem. So for those first nights, we left open the door that communicates that room with the main bedroom - which has air conditioning.
Check-in was a breeze. Our host was ready for us when we arrived and gave us recommendations on where to taste the typical Cocido Madrileño. Communication with our hosts was great - always quick to respond, always kind, and helpful.
This was the perfect opening to our family trip through Europe. Highly recommended!
