We enjoyed our 11 day stay at the Amsterdam Amstel Garden Room. Everything was quite perfect and as described or better.
The room is situated in an authentic Dutch canal house at the beautiful Amstel river and is walking distance to many points of interest, including an excellent supermarket, Albert Heijn.
The space is well-appointed and quiet and the bed and bedding are great. The kitchenette and very nice sized bathroom are perfect. To us the only negative is that the layout of the space is tight and hard for 2 people to get around each other but in every other respect this is a really great place for your stay in Amsterdam.
