We had a very nice time in Michael's house. We arrived later than the planned time because our train was delayed and Michael was very comprehensive and waited for us by the time we arrived in the night. The breakfast is amazing, very complete and more than enough. We were 5 in the group and everyone felt very comfortable in the house. The instructions to get to the house are very accurate, there is no chance to get lost if you follow them.
Overall, we had a pleasant time in Amsterdam and MIchael's place was one of the elements to make it happen.

Thanks a lot Michael :).
