We had a good time in London and May's place. The room was clean and as expected according to the pictures to accommodate 4 people. May's daughter greeted us kindly, explaining clearly all related to the place. It was a bit difficult to coordinate the first meeting given that May and her daughter are busy most of the day, so we had only a half of an hour window to meet them. We ended up waiting almost an hour to do so.
The location was relatively close to the subway, only about 15 mins walking time. Consider an Uber a good option as well.
It seems like many other rooms were used for guests, so the bathrooms were certainly busy at times. May was friendly but we barely interacted with her.
