Spitalfields is one of the oldest parts of London with great financial support from the British government to preserve structural and historical narratives within its neighborhoods. The room is located on the top floor of a room 200-300 (!) years old, and it's modernized living space excellently reflects the conservation all around it.
We only stayed one night — our last in Europe after a week in London and another in Paris — before departing early to fly out of Heathrow. The apartment is an 8 minute walk from the Aldgate East tube and about 12 from the Liverpool Street station. Without any specific historical knowledge of the area, Z & Alex's space is located in a quintessentially-London neighborhood from a bygone era (Georgian and Victorian, specifically).
If you're looking to spend time in East London, put Z & Alex's space at the top of your wishlist. Z is a welcoming host and the two will do all they can to accommodate you during your stay in London. With much to do and so little time to see it all, staying in Spitalfields is a great way to get the best of the old flavors in the new world. Great space, great hosts!
