Greta and Ruud's house was perfect for us. It is in a quiet neighborhood but just around the corner was another neighborhood of shops, restaurants and a wonderful patisserie. The apartment was very clean and efficient. A bottle of red wine was waiting for us. The tram was a block away that goes from the ocean to central Den Haag.
As hosts they were welcoming and yet not intrusive, helpful but not overbearing. When we come back to Den Haag this is where we will stay. On a scale of 1-5 they get a 5+. This however is not a place to stay if Dutch stairs are a problem. Two flights with handrails was fine for us but if you are mobility challenged think about another country.
