The room is in a great location, within walking distance to St Pancras International and King's Cross tube station. The room and bed were comfortable, and the place was situated in a quiet neighbourhood. As Ekaterina wasn't at home on the day of check-in, her sons were there to help with the check-in process and they were kind and helpful.
At the time of my stay, Ekaterina's son had informed me that the shower was slightly faulty but that they are planning to fix it. So just be prepared that you may be able to shower, but you may have to budget more time trying to figure it out in order to reach the right temperature. Another thing to take note of - the bedroom door cannot be locked. :)
Overall, it was still a comfortable stay. Thank you Ekaterina! :)
