Never gets old
I've been to London several times and I would recommend it to anyone! There's a lot to do (sometimes too much) and if you've seen it all, you can still walk around and find amazing other areas of London. The parks are beautiful and the attractions are amazing. Museums are mostly free and usually everywhere has a student discount. The city can be a bit pricey but you have to be smart about where to eat if you're on a budget. Cheap places are off the tourist path and are usually better anyways
Insider Tip:Get an oyster card and learn the bus system. The buses are cheaper and you get a great view of the city.
