We were a group of 10 traveling to Amsterdam on a study trip from the States. Marco's house was wonderful for us -- spacious, clean, and individual beds for all. We were a bit anxious about only 1.5 baths, but it ended up working just fine with a little advance shower-planning! Marco was a fantastic host who was very responsive and accommodating. Location is a very short walk from the concert hall and main museums; the trip into central station is a beautiful 2 mile walk through the canal district and center (of course, one could take the trams, but we chose not to!). A very good experience. Highly recommended.
