My room was a 3* one with 2 windows opening to a brick wall and the roof of another building. It was like a dorm room with a double bed, an IKEA-like rack for hanging about 6 items of clothing and blue carpet on the walls and ceiling. There was a separate room for the bathroom and one for the sink and shower. Mind you, the shower/sink is a wet bath, every where gets wet and it smelled a bit like sweat. I had to pay in advance, which I found was odd, as every other hotel I stayed at, I paid at the end of my stay. If you're looking for a place to crash, this hotel is ok, but if you're planning on staying longer or if you have a lot of luggage, look somewhere else. My 3* room would be too small for two people. It was even too small for one person. There was no central lighting, just a light above the landing at the entrance and 2 bedside lamps. A bit dim.
This hotel is not like a traditional hotel with lobby, or business centre. It's possible to even miss the entrance to this hotel as you just see a door. It is tucked away between the Stock restaurant and a halal restaurant. A narrow hallway leads to the reception in cubicle. The surroundings of the main entrance was a bit crowded, as there were tables and chairs outside, so you sort of have to navigate through whatever space is left.
My room had stairs leading to the door, then stairs leading to the bedroom. So if you have a lot of luggage, even the wheeled luggage won't help you out. On the upside, my room was quiet and clean and I even had a change of towels even though I did not request my room to be cleaned. The location is a plus, as it is a few steps away from Central Station and on the same street as the tram line, it is in the heart of all the tourist attractions.
Yes there was not storage, no closet, no desk or chair (I put my laptop on the bed). And no A/C, just a fan. The website doesn't really reveal much in a way of amenities--check tripadvisor or expedia.
For the same price, it's possible to find a room at a 'traditional' type hotel offering more: a regular bathroom, storage, business centre, table, chairs, mini-fridge, kettle, coffee maker, AC. For my next stay in Amsterdam, I would book somewhere else.
