My husband and I just stayed two different times within the past two months (our trip was from mid May to mid June) in the same Airbnb near Paddington, and the Bayswater and Queensway tube stations. We loved our location since we arrived to Paddington from Heathrow on the Heathrow Express. Plus we could easily purchase Travel Cards at the train stations and get Oyster cards as well as top up at Paddington (and other stations too). And we had other travel in England and we left from Paddington. The location was excellent for transportation and sight seeing.
Although the Patio Studio near Bayswater and Paddington may well be booked through the summer they may have some recommendations of other Airbnb's nearby they know are good.
These hosts were probably the top hosts we have ever used and we have used some good ones. I found when I began searching Airbnb's in London in November 2016 daunting. It took me months to go through all the listings. I knew what to look for and finding a host who doesn't cancel, and one who has absolutely top ratings plus at a reasonable price was a long process. I was so comfortable booking this listing for the first part of our London stay that I also booked the remainder of our trip with these hosts. They had guests for four days previously booked so we made a trip to see friends in Wales, and returned to this listing. The second stay did not disappoint.
We have now stayed in a total of 22 Airbnb's starting with our first and only in 2014 to now 2017 after our trip. So we are pretty clear in what we look for as a couple in an Airbnb. The place we stayed in London would be great for one person, or two people and fine for four people who are related. (No they didn't ask me to do this, but I believe in sharing this type of information for those looking for an Airbnb.) My husband and I always try to book Airbnb now.
Good luck, Sonja
