We had good stay in Paulo's flat. I never met Paulo, but talked to his colleague - Paul. He was very friendly and helpful. Very good communication.
For facilities, beds were comfortable. Rooms are big. They also have storage room for extra space. Dishes, folks, cups were provided, and you didn't need to wash it. Paul picked up our trash almost every day. It was very kind.
Location is good. Quiet and safe neighborhood. Many restaurants and bakery nearby. 5 mins walk to tube, overground, bus and train.
For parts need to be improved:
Hot water was a bit issue, we need to keep resetting the hot-water heater once a while (every two or three days) to keep hot water going.
Also there was water leaking issue in restroom. Every day we need to turn on/off water valve if we need to use it. It was annoying.
wifi was not stable. sometimes I could not connect to it.
Also be aware that, their office was right next door to us. Sometimes I could hear their talking and working. It was not a big problem. Just not feel 100% private.
Overall, it was a nice place to stay in London with minor issues.
