Communication was very good from host.
East check in for the key - nice after a long flight.
Location is good; next to a park, quiet street and 10-15 min walk to museums.
Very clean.
A bit small, OK for 1-2 people max, but does get a little cramped with luggage, etc.
Beginning on Day 2, they were doing concrete work literally outside the door of the flat - while not the fault of the owner necessarily, it would have been nice to have known as we would have went elsewhere... no one wants tools and drilling 2 meters from your bed early in the morning when on Holiday and especially in Amsterdam. ;-)
