Yoshi was a great host. The room we stayed in was clean and spacious for two. He has a cat but it was not a bother to us at all. The bed was comfortable. He provided us with transit cards and he gave us a list of hot spots in the city.
His place is located in the north part of the city. It is a quick bus ride or bike ride to Amsterdam's central station; about 10-15 minutes once you cross with the ferry, which is free of charge. Yoshi allowed us use his bikes and provided us with a key so we could come and go as we pleased.
The stairs to our room were a little steep but Yoshi offered to help us carry our bags. He has one washroom located downstairs and a shower located upstairs; both were clean.
