Communication with Kristina was very easy. She was not there during her trip, but one of her friends was there to welcome us. We even got to check-in a bit early which was very convenient. The location is great (10 minutes away from the tube/train station and close to the C10 bus) and the apartment was quiet. The only issue was that we were there during a heat wave and there was no fan nor mosquito nets on the windows (we got quite a few bites!). I told Kristina and she said that she will take care of the situation for future guests. :)
