We had a great time at Julie's house. With public transports nearby (5 minutes walk) you can get quickly to the center of London. In addition some of the busses drive 24 hours. So the location is very good to explore London and it's sightseeings.
Even though the room is not that big its perfectly fine for sleeping in it. Also there was not a problem with the shared bathroom and toilet! You can not use the kitchen but there's still a possibility to have your breakfast in her sitting room. Furthermore, you have a tiny fridge and a water boiler in your room, which is great.
In conclusion it was very good for a short term stay in London. Julie was very friendly and she made us feel comfortable. Thank you and all the best!
