We stayed at May's house for the week. This was an excellent stay! House is beautiful (better than the pictures) with ample space to lounge and a wonderful kitchen. For sightseeing (Big Ben, Buckingham palace, etc.), we mostly took Uber (20-25 min ride) but you can easily walk to the subway (Shepherd's Bush Station) as well. On some days, we simply stayed local (15 min walk to Notting Hill and Portobello market) and had a great dinner at Casa Cruz (less than 10 min walk). I have been to many AirBnb's and highly recommend May's place.
