I haven't stopped talking about this experience since I returned to the states in April of 2013. From the phenomenal housing to the always-going social scene, the depth and breadth of free art, the fact that you're a train ride away from nearly anywhere you'd want to come in Europe...this study abroad experience is one I'd recommend to anyone.
While I didn't find FIE itself hugely helpful, the professors I studied with were engaging and entertaining. I cannot emphasize enough, as an English nerd, how much I loved studying Shakespeare in London, touring the Globe, and seeing a modern retelling of Twelfth Night. The British culture course was also just an interesting way to engage with the city.
The most wonderful aspect of FIE is the housing/transportation included in this study. I doubt I will ever live in as upscale a neighborhood as FIE's South Kensington apartments; even though I lived on the top floor of a seven-floor walk-up, being in central London was utterly worth it. The area is safe and hugely accessible. There are plenty of small grocery marts and cafes (there was a new, to-die-for French pastry shop literally around the corner from my building on Manson Place, with meringues as big as your head).
It's a few minutes' walk from Hyde Park & Kensington Gardens, the V&A and several other museums; it's the perfect place to stay and be connected to the city. This program also knows how important transportation is in London and supplied us with Tube & bus passes, which lifted what could have been a big part of financing the experience and allowed us the freedom to travel wherever we liked within the city. They also offered some discounted trips, tickets, and experiences like high tea at the start of the term, which was a great way to plan out some London-sightseeing throughout the year.
It's fairly simple to buy some inexpensive towels and bed linens at stores like Primark (the UK version Marshalls), as you're on your own for the former and the latter were a little sparse, at least in my building. But the experience...looking back, my appreciation for those four months only continues to increase.
And, not to give anyone absurdly false hopes or anything, but Englishmen and Europeans are lovely and direct (being asked out on a date, straightforwardly, is nice!). I very happily met a man I fell utterly in love with while in London, and our first date walking up and down the South Bank of the Thames, followed by cooking dinner at the flat I stayed in, remains one of my fondest memories there.
