He had a great experience at Louis' home. The house is beautiful and charming, it's in a great location (15' to city centre) it has 2 very good reataurants aside and a supermarket crossing the street... Everything you need to rest after sightseeing.
(Only the stairway to the bedrooms is a bit challenging.)
If you like running, Vondelpark is close too.
Louis? He is a Cool guy and everything was alright with him.
I would repeat if I come back to Amsterdam.
