Rey and his partner were really welcoming, nice and flexible during check-in. The room was as it has been described, nice and clean. We could freely use the shared kitchen and bathroom. They also had nice tips for good restaurants nearby.
Only negative point is that the room is next to a busy street, which makes it a bit noisy, but this hasnt been a problem for us at all.
Would definitely recommend them as host and book their room again when we're in London again.
