The two hosts, Parag and Henry are unusually charming and helpful. They were really more like friends than hosts, and anyone staying there should ask them for advice on taxis, museum cards and travel cards.
The room was exactly as described: very clean, within walking distance of everything interesting in Amsterdam and with a tiny garden where you can relax a little with a cup of coffee or tea. Nearby, there are excellent places to have freshly cooked breakfast, and the metro station is 3 minutes away, not that you need to travel much by metro, as two bicycles are provided, and in Amsterdam cycling is the preferred mode of transport for all ages.
5 stars.
