Budapest earns every superlative thrown at it, and I say that as someone who has grown genuinely skeptical of European city rankings. I spent four days there last spring and came away convinced it belongs in the same conversation as Lisbon or Porto, cities that reward you for actually showing up rather than just ticking a box. There is a particular kind of city that gives more the longer you stay, and Budapest is exactly that kind of city. I have watched friends spend forty-eight hours there and leave satisfied, which is the saddest possible outcome, because satisfied is not what Budapest is going for.
Start on the Buda side, specifically the Castle District, and give it a proper half-day. Buda Castle is enormous, and the views across the Danube toward Pest are the kind that stop you mid-sentence. Go in the late afternoon when the light comes down at an angle and hits the Chain Bridge just right. Walk the cobblestone streets without a plan, step inside Matthias Church, and resist every impulse to rush toward the next thing. The hilltop has a slower, older quality that the rest of the city simply does not have. That said, once you have absorbed it, you have absorbed it. Cross back over and don't look back, because Pest is where the trip actually lives, and you will feel that the moment you reach the other bank.
In Pest, yes, go to Szimpla Kert, the original ruin bar in the 7th district and still the best execution of that concept by a wide margin. Go once, on a weekday evening, and then move on. The food scene is what genuinely surprised me. My strongest recommendation is Hala Koszyki, a beautifully restored market hall on Klauzál tér with somewhere between ten and fifteen stalls running the range from Polish classics to solid sushi to very good burgers. I ate lunch there three times in four days and have no regrets about any of it. The bill came in under fifteen dollars each time, the room is gorgeous, and the place is full of people who actually live in the city. That last part matters more than most travel advice admits. For where to sleep, book the 5th or 7th district and spend whatever you save on airfare stretching toward a nicer hotel. Budapest is dramatically cheaper than Prague or Vienna, and a good apartment with a proper view of the city will change the texture of the whole stay in ways that are hard to explain until you are sitting there with a coffee watching the street come alive below you.
Skip the thermal spa packages sold through hotels entirely. Széchenyi Baths are worth your time, but buy the ticket directly, show up on a weekday morning before ten, and you will have an entirely different experience than the tourist scrum of a Saturday afternoon. If you have a third or fourth day, take the train to Esztergom and Visegrád along the Danube Bend. Almost no one does this. Almost no one should skip it. The ride alone, following the river out of the city through increasingly quiet country, is worth the few hours it costs you. Book somewhere in the 5th or 7th district, go to Hala Koszyki the day you arrive, and save one full morning for the Danube Bend. Those three decisions alone will separate your trip from everyone else's, and you will come home with the slightly smug satisfaction of having gotten a city right.
