This apartment is clean and cozy and has everything you need. Egbert is a terrific host and has accurately described the apartment in his listing. We arrived in blowing snow, and he came out to help us with our luggage and give us an introduction to the apartment and information about the area.
To get to the apartment, you have to walk up a gangplank and then down a narrow space of deck toward the front of the ship. Then, it's down the hatch. The stairway down turns 180 degrees and is more like a wide step ladder than stairs. So, you'll want to pack lightly (which is the best idea, anyway). It also helps to be fairly agile.
There is a nice little neighborhood pub nearby (De Oceaan). We ate there the first night because Egbert recommended it and because it was so close and the weather was fairly nasty. We loved it so much we went back the next night.
We loved our stay on the Maria, and would like to stay there again sometime.
