It was definitely one of my best experiences with Airbnb. Communication with David and Savie was excelent right from the beginning and my check-in was a breeze. I didn't have a chance to meet David personaly, but he seems to be really great. I've met Savie and their son Rugare though, who were both absolutely lovely and very welcoming.
The room was small, but nice and very clean, just like the rest of the apartment. The neigbourhood is calm and very well connected with the center of London - it only takes a couple of minutes walking to reach the Oval underground station.
Would recommend and will come back!
