We stayed here for a night during a recent trip to Madrid. We picked it because we wanted to catch the airport express bus near Atocha early in the morning and wanted something walkable. The hotel looks a bit dated from the outside, but the room was surprisingly updated and new. Large room, nice bathroom, free wifi in the lobby, good service (they printed out our boarding cards and were helpful with directions and general info). Some noise from other rooms/ outside, but was not intolerable in any way. Overall a good value stay near the station/reina Sofia etc.

Located about 5 minutes walk from the Atocha metro station, near the Reina Sofia Museum. While not right in the heart of the city, it is pretty central as Madrid is very walkable, and of course you can always hop on the metro at Atocha. Also very convenient if you are arriving or departing by train, as the Atocha Renfe train station is also 5 minute walk away, saving you a cab ride or lugging your stuff on the subway.

Very comfortable bed. Plenty of desk space for my laptop. The room had a small fridge/minibar – which had some water, sodas and juice and was free! Room was clean. Nice, modern bathroom. Staff was friendly and you can leave your bags with the front desk after you check out if needed.

My room rate did not include breakfast.

Internet – in the room – is extra. However, there is free wifi in the lobby.

A simple map on the hotel's web page would make getting here much easier. It's very simple once you figure it out.

The bed was very comfortable, linens clean, but the room is dated and lots of scrapes on the wall indicate that the room hasn't been painted in a few years. Noise is a problem here ... the hotel is in a U shape, so 4 doors are within feet of one another. If you like a place where you can hear slamming doors this is it.

Wi-fi in the room is too expensive. Also no in-room coffee boiler or refrigerator.

On balance this is an OK place to stay near the railway station, but I don't think it's a good overall value and definitely not what I expect from a Marriott-related hotel.

The hotel is perfectly situated for a trip to Madrid. It is no more than 5 minutes by foot to visit the "Reina Sofia" and no more than 20 minutes by foot or approx. 5 min by subway from "Puerta del Sol" and "Gran Via".
Coming in from the Barajas airport, the hotel is situated in direct neighborhood of the Ceranias Renfe station of "Delicias" as well as the metro station of "Palos de la Frontera" (not sure if i remember the name 100% right). If your flying Iberia you will most probably land in Terminal T4 of Barajas, which has a station of Cercanias Renfe. There is a direct train, which takes about 30 minutes.
We had a standard double room, which was clean and reasonably big. The furniture looks rather new and stylish. Very surprisingly the minibar was included in the fare (although there's no alcoholic stuff). The clerks we were talking to have all been very nice and helpful.
