Very convenient, and Joan was very responsive.
However we had a lot of difficulty with the check in process (very time consuming online process in the lead up to the booking, and impossible to get access into the building on the day because we couldn't get internet access through Orange or Vodafone from the street outside the apartment + hard to get help by telephone) which took us by surprise as we had 5 other Airbnb bookings in the weeks before without any problems.
