We had a standard room for one night here. It was very simple and a little out-dated. The service was fantastic, staff were very helpful and friendly. But the room was a let down. We paid $480 pesos (US$120) for the standard room with queen bed and it was basic. We stayed in a hotel that was only $20 for a double room and the bed maybe wasn't as comfortable but there wasn't much difference in room size or amenities.
The breakfast was fresh and simple continental style. The view from the top level small restaurant of the snowy mountains was fantastic!
It just wasn't worth that much money.

Location is great, wi-fi works very well,, rooms are adequately sized and stuffed. Not luxury, but the price is quite affordable and honest.

Overall, for the value and need, the hotel was nice. Its location to the tourists locations and restaurants was very close (walking distance) and only a block away from Independence Plaza. The people were very friendly and service minded. The language barrier was tough to overcome unless, but overall I would stay there again.

The only thing with merits the term "Gran Hotel" is the room size and the bed quality. The rest is an average middle class hotel, which needs at least a touch up for its price level of 100 US$ per night. You have the choice between thin windows to the street crossing in front of the hotel or a nice look at a badly painted concrete wall in the backyard. On top are cracked tiles with fungus, old furniture, a smoky smell, a dust-stuffed air condition, a defect in-room-safe and a lousy, mostly pre-packed breakfast: You can have all this somewhere else for half the price. Therefore I call this place a ripoff and recommend you the "Hotel Argentino" in Mendoza for two thirds of the price.
