If it’s your thing…The Prado or Thyssen-Bornemisza. The Reina Sofia is ok but only has Guernica, the rest is pretty awful
We always go the the Parc del Retiro and spend at least 2 afternoons in one of the bars slowly sipping beer or sangria. It’s super relaxing. There’s also an exhibition building there that can have some interesting stuff. And the Crystal Palace
The centre is very compact and you can walk everywhere
The Mercado de San Miguel is very commercialised/touristy, but definitely worth a visit. It’s very close to the Plaza Mayor which is ok for a drink in the evening. They both sit at the top of the street that has all the tapas bars that you should wander down and see what’s on offer
The Royal Palace is worth a visit, if it would be of interest
I keep getting recommended Sorolla’s House but haven’t been there yet
There’s so much choice when it comes to restaurants. The only one we go back to time and time again is Casa Julio for croquettas at lunchtime. Dirt cheap, very small, but does feel authentic, although the owner has had to respond to lazy negative Tripadvisor comments and now makes attempts at conversation in English which detracts! It also forces you away from the Gran Via through the Salamanca district
We had a great meal at Juana La Loca, but prebook and get google lens working
How useful this may be someone travelling with an 18 y/o, I don’t know
Ahh, just remembered the Naval Museum. Cheap and recently refurbished. Just right for an 18 y/o. It’s near the Parc
We love Madrid, it’s a great city
Edit: I knew I felt like I was repeating myself
