I had wonderful stay in Alex's apartment.
Alex is an extremely warm and friendly guy, relaxed, and very helpful with tips and help whenever any was needed. He went out of his way to allow me drop my bags off early on day one, and leave them late on the day I was leaving to make life easier for me.
Alex's apartment is really clean and nicely finished. The bed is super comfortable, room plenty large, and the shower and kitchen facilities ideal. It's also quiet.
The apartment is located just a couple of minutes walk from the top of Brick Lane, which has a great atmosphere and a mix of eateries, art, and things to see. There is a great market there on a Sunday, and real vibrant community. I walked extensively and never felt anything other than safe in the area. Heading in a different direction from the apartment, it is a short walk to the Columbia Road Flower Market on a Sunday, and the Hackney city farm, both of which are quirky and great places to relax and eat.
The public transport is quickly accessible, but if you like to walk, from Alex's apartment, it is only a 20/25 minute walk to the Tower of London, from which you can set off exploring the city.
I had the best of both world's staying here, a nice place in a vibrant borough, with ease of access to the city for meetings and exploring.
Highly recommend staying at Alex's place.
