Marta is a very helpful host providing all the information the guests need prior to check in. She could not be with us but her friend Paula is just as nice and helpful.
The apartment is kept very well, we are impressed with the variety of food, spices, and kitchenware for making breakfast!
Another thing is we love the huge and spacious living and dining room on the ground floor and the little garden as we are family travellers with young kids. Martas place really gives us a feeling of home away from home.
Location wise, it is not in the most central location, but only 20 minutes bus ride from Centraal Train station. Plus our interested sightseeing spots are all in the suburbs, the free parking is more important to us than its proximity to the city centre.
Overall I wouldn't hesitant to recommend the Room Downstairs.
