My sister and I spent a week at Joanna’s flat and found it was a perfect “home base” for our week in London. Joanna is a really lovely host and was very welcoming and ready to answer any questions we might have about the area, transport, etc.
The flat is clean and stylish, and it is located in a quiet neighborhood right on Portobello Road. There is easy access to the Portobello Road Market and a very nice selection of restaurants nearby. There are bus and tube stops within a 10 minute walk of the flat that make it incredibly easy to get to Central London and to various railway stations in case you want to take any day trips (we did both Oxford and Canterbury)
Easily a 5-star experience. I highly recommend Joanna as a host.
