We stayed two nights at John's place - it's a lovely apartment and John was really nice and helpful with recommendations. The flexible check-in times were great for us as well. The place has a great location for exploring east London, while central London is easy to reach too. There are some nice cafes and restaurant just around the corner and it's just a short distance to Shoreditch (for going out) and to some fantastic local markets. We would definitely stay there again.
