We stayed in the apartment for 3 nights and had a lovely time. The apartment is fully equipped with everything you will need and proximity to Old Station (which we took most trains from) is a quick 5-7 mins walk. I've been to London a few time and I always enjoy exploring Shoreditch and you can cover pretty much all of it by foot from the apartment.
Having said that, the apartment is quite small and with luggage and 2 people..it can get quite cramped. We found the back street that the apartment is on to be a little shady, so walking home at night was not the best experience.
Overall though, I'd definitely stay here again!
