I would highly recommend a stay at Priyanka's place. The apartment itself is lovely and it is in a beautiful neighborhood just down the road from Abbey Road studios. There are two underground stops that are in a 5-10 minute walking distance from the apartment and you can be in central London in less than 15 minutes! The local neighborhood has an assortment of great places to get a meal - I highly recommend Gail's bakery, The Peppermint Cafe, and Tamada (Georgian food).
