I stayed at NH Sur for one night as it is right across from the main station, Atocha, and very close to the metro line to take you to the airport. The room was small but clean; no view but that meant it was quiet.

Staff at the desk were accommodating when my TV would not work. Nothing too special but a safe and clean hotel in a good location.

I booked a room in the NH Sur after two excellent experiences in other hotels of this franchise (in Salzburg and in Dortmund) and this one was definitely not as good. The room was quite small and nothing particular in terms of style or atmosphere. Perhaps the worst was the wood floor, that was badly worn around the bed. Traffic noise is a problem but to be fair I have to recognise that the hotel management have done their best (there is a double window) but if you have sleep problems just ask for a room not facing the street. The good news is that air conditioning was faultless, so there was no problem in getting the adequate room temperature.

If the room was not something to remember, breakfast did lighten the day: they had perhaps the best orange juice I have had in a hotel for a long time, and the rest of the food was also of a high standard. Free newspapers were also a nice detail.

The NH Sur was right across the street from the Atocha train station, which was incredibly convenient. I paid about 150 Euro for 3 nights, whcih was a fantastic price. Super close to the "golden triangle" and with the new bar/restaurant at the Reina Sofia, a great place to eat/drink just a couple of blocks away. Although the room was tiny, it was spotless, well decorated & the bathroom was spacious, and the staff was unbelievably helpful. Staying with a respectable chain was great for the services -- i got sick my 2nd day in Madrid, and they had a doctor come do a "house call." Was feeling better in less than 24 hours (and as it was my first stop in Spain, was grateful for not having to figure out where the hospital was, etc.) I would highly recommend it for a short stay especially if you plan on traveling by train. For a longer stay it might get a little cramped. Request a room on a high floor with a balcony.

We stayed at the NH Sur in Madrid for two nights and were very happy with it. While the room was quite small (to be expected in Spain), it was still quite comfortable with very modern furnishings and a great, marble tiled bathroom. The lobby is nothing to rave about, but this hotel makes up for it in its location. It is across from Atoche train station and very close to all the museums and Retiro Park. It's about a twenty minute walk to Plaza Mayor, or 5-7 minutes by subway. In all, we really liked this hotel.
