The and is intentionally misleading. Uses language that creates an image of a hotel. "Spa and wellness center" = nail salon in the same building. "Deluxe double bed room" = small room two beds crammed in. "Welcome drink" = I guess the water bottle? No pool or garden.
"Shuttle to airport" = they give you a ride that cost 30 €, hotel shuttles are always free.
This is simply a private flat with two extra rooms that they try to make sound like some hotel-like beach hostel. They were friendly, but they intentionally mislead.
