This is a great place to stay if you are on a tight budget. I only stayed for 2 nights and everything was pretty much as expected and as listed in the description. I had a small private room in a shared basement apartment. One of the other guests in the apartment had left some food out in the shared kitchenette which attracted a few ants, but the host, Sohail, cleaned it up and everything was perfect after that. The internet worked great, the room was a comfortable temperature and clean.
Very easy to find - it's located directly across from the Bayswater station on the circle line. Lots of shops and restaurants in the area. Walking distance to Kensington Gardens.
Sohail is a fantastic host and very tech savvy (he has a mobile shop above the airbnb.) When I first arrived he helped me figure out how to get my new sim card working on my phone (I am from the US and had purchased one at the airport but couldn't get it to work) He was able to answer all my questions about where to find things and ideas for exploring/sight seeing. Very easy going/friendly and great communication.
