My partner and I stayed for two nights on a weekend. We didn't get to meet Yu, but he sent us a helpful video about how to get into the flat and unlock the very tricky door. This was a mostly positive experience-- convenient location, clean room, moderately comfortable bed, good neighborhood. the price is really good for this location of London, so it is hard to pass up the opportunity to stay here! However, do be aware that there is at least one other person living in the house, and the kitchen is Right next to the room you'll have, so if it is in use or the housemate has guests, it can be quite loud. I also recommend bringing an extra towel if there will be two of you in the room, as only one was available for our stay. Overall a good experience, young.
