When I arrive in Amsterdam it is generally at the end of a 14-hour plane and rail journey, and I appreciate nothing more than the quiet and comfort of the A-Train.
Location: As you might gather from its name, the A-Train is just a few blocks from the train station. It is within easy walking distance of Dam Square (2 blocks to Damrak and 3 blocks up to Dam Square), a big shopping center and the city hall (for both: follow the Singel canal to Radhuisstraat).
Facilities: There are at four storeys of guest rooms on two unconnected sides of the hotel. The hotel's buildings are a historic landmark. I say "buildings" because it looks to me the inside of the hotel was once two adjacent buildings that were joined together sometime in the past 200 years. Because of this, the A-Train's layout is rather random. Some rooms are very spacious while some are cramped; bathroom facilities and furniture can very widely from room to room.
Decor: The rooms are decorated plainly, but well. Some rooms' bathrooms are "wet," i.e. there is no divider between the shower and toilet/sink, and the entire bathroom is designed to get wet.
Amenities: The linens are clean and the room is free of dust. No coffee maker, iron, television, etc. AND -- the biggest disadvantage to the A-Train -- no air conditioning, due to their historic landmark status. There is a fan in every room, but does no good on a warm day. Get out of your room and enjoy the sights!
Extras: The free continental breakfast is well done, with all-you-can-eat: ham, cheese, croissants, rolls, cereal, yogurt, milk, juices, and coffees/teas. Get down to the lobby before they stop serving or you'll have to fend for yourself on the expensive streets of Amsterdam.
