Jo was a very good host. We very much enjoyed our stay and we are really thankful for her hospitality. Jack and Cara, Jo's son and daughter, were also very kind to us. They also have a cat, John, that is very adorable.
Her place is located in a really nice neighborhood. It is two blocks away from Portobello market, a famous market in the city, which is open on Fridays, Saturdays and Sundays. You can also take the 23 to go to Trafalgar Square. It takes only 30 minutes to go from Jo's place to the center of the city.
The lounge and the kitchen are not available to use, but that was Ok with us. If you are planning to be in the city during the day, this is a very good place to sleep at night. Although we only had a room for us, we had enough space for putting our stuff (2 backpacks).
Overall, we had a very good experience.
