Maria Christina replied quickly and accurately to all my queries. The accommodation was ideal for what we wanted: a convenient place to stay the night before flying out from Heathrow. Bus service is almost outside the door, recommend using a bus app to predict times accurately. It was approx 15 minute walk from Hatton Cross tube. Room was basic, but all we wanted, clean and comfortable. Note no amenities in room - no coffee or tea making etc. - but that was fine for us, we left early so didn't need it. Note also there is only one shared bathroom, as the description says. Factor in wait time for shower in the morning if someone else is using it, of course. Efficient check-in system did not require host involvement, which was fine, so we didn't meet the host and did not need to.
Overall, did exactly what it said on the tin.
