My boyfriend and I didn't get to meet Alex, but he gave me instructions on how to obtain the key and get into the apartment. He was very quick in replying to any questions I had as well, so everything worked out great in that respect. The room was a good size with a bed big enough for two people and enough space to leave suitcases and even unpack some stuff. There were other people staying in the apartment while we were there, but we hardly noticed or ran into them, as we went sightseeing most of the time. The apartment is in a great location in Shoreditch, close to lots of bars, cafes, and even in walking distance of some sights - Liverpool St Station (several tube lines, national train lines, airport express...) is about 15 minutes walk, it's possible to walk to the Monument, the Tower, and other sights in the city, even though there are loads of buses as well. Overall, I think it was a good decision to stay at Alex's place and would definitely recommend it.
