Loved staying at Karins place. Both Karin and her partner are lovely people! Karin let us leave our luggage there early and allowed an earlier check in because of the time we flew in. Karin was friendly and helpful giving us tips on great places to check out while in Amsterdam. The place was tidy, great heater, bed was soooo comfy, wifi connection was great, location was AMAZING. Walkable to everything close and easy to hire a bike. The only down side is not having a Tv but we were aware of this prior to booking. You do hear street noise as the city doesn't sleep until about 5am but if you aren't a light sleeper than it isn't an issue. Wonderful place! Would DEFINITELY stay there again when returning to Amsterdam :) I personally loved it there!
