Brief assessment: the apartment in Döbling is fine; the host came over on the first day and not again, but did check on us via email once a month; it was warm and comfortable and there was plenty of room for us and our grandchildren’s visit. Some care is necessary: the ventilator fan is the toilette is noisy and water drips down from it, several light bulbs went our and were difficult to replace because they are so high up on the walls. Our only real complaint is having to pay extra for visitors, after we paid the full rental price. Don’t know if this is standard for AirBnb (??). If we return we will seek a different apartment for several reasons, price and location in particular.
