There was leaking problem from the upper level's bathroom. Water dripping to lower floor's ceiling happened after we used that shower room. We didn't use that bathroom afterwards. The cleaner came to knock our door at 9am on our check-out day and insisted to ask for coming in to start the cleaning. We were too nice to let her to come in to start cleaning up the top floor's bedroom at 9am. However, she kept walking up and down to ask if it was okay to clean up other area which was kind of rude and annoying to us. We were still very busy packing the baggages and having breakfast with our three-year-old kid, and there was a stranger walking around that little house. I really hope the next family won't need to experience that. Overall, Sandra's house was in a peaceful neighborhood and we had a nice stay there. But just a friendly reminder, it takes a 45mins to an hour from the property to most of the tourists' attractions such as British Museum or London eye by Uber or driving.
