Our stay at Alex's was great, the flat is very well equipped (iron, cooking tools, shampoo, washing machine, ...), clean and comfortable (even if the bed was a little bit too soft for us).
The location is excellent, the flat is nicely located in Shoreditch, close to tube and bus stations. It really is enjoyable for a stay in London. Yet the flat is located on an extremely loud street : there is a club below and an other one in front of the flat. The windows let the sounds of the clubs and of the people on the street in, making it unlikely to have a nice resting sleep. Especially since you are awakened quite early at the sound of the garbage truck collecting the glass bottles.
The value of the flat is still great since the flat is really inexpensive given the location and very well equipped, yet the noise was too much for us.
