The short answer
For a first visit, base yourself in or beside the center so the famous half of Madrid is a walk rather than a metro ride. Sol and Gran Vía put Plaza Mayor, the Royal Palace, and the big museums within twenty minutes on foot, which is exactly what you want when you have three or four days and a list. The trade is noise and smaller apartments. If that worries you, shift one barrio out to Salamanca or Chamberí and add a ten-minute walk in exchange for quiet and space. Every one of those choices is a good first trip. There is no wrong answer here, only trade-offs worth understanding before you pay.
What "central" actually buys you
Central Madrid is genuinely walkable, and that is the whole case for staying in it. From Sol you can string together the Royal Palace, Plaza Mayor, the Prado, and a Gran Vía dinner without touching a train. For a short first trip that saves you real time and real transit stress. What central does not buy you is calm or square meters: the streets around Sol and Gran Vía stay loud past midnight, and the apartments trend compact because the buildings are old and the demand is relentless. If you sleep lightly, read the next section before booking the most central option you can find.
One honest caveat about the very core: a handful of blocks right on Puerta del Sol and the top of Gran Vía are more tourist thoroughfare than neighborhood. You will do fine there, but you will not meet Madrid there. Staying a few streets south toward La Latina or east toward Malasaña keeps you walkable while giving you a barrio that still belongs to the people who live in it.
The calmer alternatives
Salamanca is the easy upgrade: wide, quiet, safe-feeling streets, larger apartments for the money, and a fifteen-minute walk or one metro stop to the museums. It reads a little formal and a little expensive, and that is the point. If you would rather have neighborhood life than grandeur, Chamberí is the local's choice: plazas full of residents, excellent everyday food, and prices below the center, at the cost of a slightly longer walk to the sights. Both are calmer places to come home to after a full day, and neither will keep you awake.
Our favorite first-visit stay
If you want the center without gambling on it, one property keeps winning for first-timers: a fully digital aparthotel with kitchens and laundry, the deepest reliable review record in our central set, a short flat walk to Sol, Gran Vía, and Plaza Mayor:

Getting in from the airport
Barajas sits northeast of the city and connects three sane ways. The Metro (line 8 from the terminals to Nuevos Ministerios, then a transfer) is cheapest but stair-heavy with luggage. The Exprés Aéreo airport bus runs to Atocha around the clock for a few euros and is the calm middle option. A taxi is a fixed flat fare into the center, which is the one to take late, tired, or with a group. From Sol or Salamanca you are roughly thirty minutes from the terminal by any of them. Whatever you book, confirm the building has an elevator before you commit: "second floor" in a Madrid building can mean three real flights with a suitcase.
First-timer mistakes
Booking the most central address you can find, then losing sleep to it: the difference between Sol and one barrio out is often the difference between a good trip and a tired one. Assuming "sleeps 4" means two bedrooms, when it usually means a sofa bed in the living room. Skipping the elevator question. Planning museum mornings and forgetting that the Prado, Reina Sofía, and Thyssen all sit within a ten-minute walk of each other, so you can base near them and see all three on foot. And underrating the walk: Madrid's center is smaller than it looks on the map, and the best way to learn it on a first trip is to stay in the middle of it and use your feet.
