Hello

There is so much to see in Budapest... I would for sure do a Danube Cruise in the evening. Since August 20th last year it has received new flashlights in the evening making it more beautiful and magic than ever. And, after all, Budapest is beautiful in the evening with lots of bridges and buildings illuminated, so I can warmly recommend that. I would also take a swim in the Szechenyi Thermal Bath, it is amazing with the hot springs outside. There are indoor pools as well, but the outdoor pools are amazing, especially if it is a bit cold outside. I would also make sure to taste some Hungarian wine in a winetasting or next to a meal, you should for sure taste the Goulash soup. These are just some advices and thoughts

Good luck and happy travelling!.
