We got an upgrade because of unfortunate circumstances of Christina. So we got the lovely upper room. It has a cozy bed, shower and toilet in the room. It's London, so don't expect huge rooms and you'll be out most of the time anyways.
You can use their kitchen as well.
Communication with Kim (co-host) and Christina was very good and the ensured that we have a great stay. We got very detailed descriptions of the house, how to get in, how to open/close the door. It sounds a bit difficult at first, but it's not.
The house is located on a main road, so you might hear the traffic slightly. We're used to quiet surroundings and it didn't bother us! But hey, you're 10min walk from King's Cross!
Thanks Christina, Leslie and Kim for having us! It was a pleasure and it's nice you're always there for a little chat!
