We stayed at this hotel for one night prior to a cruise. The hotel is located in the heart of downtown Santiago and is convenient to the various tourist sites in the town. The rooms are average but clean and adequate. It would not be a hotel we would stay in for the experience but is certainly all right for a brief visit in a convenient location.

The Diego de Almagro Downtown has 4 stars, but looks more like a 3 stars.
The room we were in (nr. 703) was very small, the bed was size was between a single and a queen size. the room was in need of a good renovation, while the bathroom was new, but very small.
the window, overlooking the noisy courtyard (with a very small pool always shadowed by the surrounding buildings), was not sufficient to light up the room, maybe because of the layers of dust covering it on the outside.. ask for rooms overlooking the street: they will be noisy as well but at least you will have something too look at and you will see the sun.

the breakfast was average, but you have to be there at the latest at 9.30, or you will miss most of the (good/average) stuff they serve.
you have free internet access from the lobby (only) computer, unless you meet the guest who spent hours playing at online poker while we were ther (but this is not the hotel's fault..)

the service is good, with friendly staff at the reception. the location is very good, just beside the Entel Tower and a few steps from the Moneda.

in conclusion, look for better places in santiago, as the fundador hotel, and try the Diego de Almagro only if you get a food rate.

We stayed at the Diego del Almagro and it is certainly convieniently located. It's right near la moeda metro stop, not far from the Plaza del Armas. Parking is free and easy, although I don't recommend renting a car in Santiago (we had a friend from the outskirts of town come in and stay with us).
The only negative, and it's not very negative, is the desk (and to some extent the breakfast) staff. They don't go out of their way to greet you or help you out.

I went to Santiago on a business trip, so my company put me in another hotel named, Atton de las Condes. However, since it was out in suburbia, once my work was all done, I decided to move to Diego de Almagro.

I booked the hotel at the last minute and my rate was the normal rate; I couldn't get the lower rate of $64/night for the executive room. I saw another rate also of $59 on the web, but it seems to get those rates, you need to book a few days ahead of time.

Diego de Almagro is right in downtown santiago. The lobby is sparkling clean and the staff at the front desk was 'ok'. They were not as professional as the staff in atton, but then again, the atton hotel seems to cater to the business traveler, so at the atton, the staff was very polite and very helpful. The staff at Diego was polite, but not forthcoming with information. I found the housekeepers to be more knowledgeable on how to get around the city, than the front desk staff. By the way, i do speak spanish so communication was not a problem. The staff at the front desk did speak english as there were several english speaking guests around.

My room was very clean. The furniture (chairs, desk) is quite old, and it looks like it needs to be replaced. However, the bed was comfortable enough for me, and I have a bad back, but I slept very well.

The bathroom was so sparkling clean that I almost slipped inside as it was very slippery. I was really surprised with the cleanliness of the bathroom. I've definitely seen so much worst in latin america. One thing that the room didn't have was an alarm clock. I always wake up in the middle of the night and I look around to the first night clock to see the time, but this hotel doesn't seem to have one. I also asked for an iron from the front desk, and they said they would call me back, and never did. I had to go downstairs to get one.

Internet connection---the first 3 floors have wireless, and i was on the third floor, but my beautiful laptop died on my trip, so didn't get a chance to test the wireless. I had to use the 2 free computers in the lobby which had a fast connection. However, many guests line up to use that, but if u wake up early enough or come back from your tours at 11pm or so, nobody is waiting to use them. I was under the impression that there would be internet cafes nearby, but I walked and walked, and there was no internet cafes near the hotel---there are a few in plaza de armas, but none within immediate walking distance of the hotel. Sombody had told met there were, but I just couldn't find them. The girl at the front desk didn't know either....

Breakfast---they had 3 long tables set up with the following:
3 types of juices---peach, orange and pineapple. 2 pitchers of milk. There were 2 bowls that had cocoa in it---one dark, the other one normal quality i guess. There were all these type of pastries on another half of the table. On another table they had sausages, eggs, eggs with ham, and bread. Another table had cereal and coffee. So there was plenty of breakfast around, but the room where the breakfast is held, is quite small. first time i went there were not enough tables, so i waited about 5 minutes to finally sit down. Food was good enough so no complaints.
Way better than the american continental breakfasts for sure.

So in summary----I would stay in this hotel again as it met all my needs. I'm the type of person that is out exploring the city the whole day, and just come to my room to sleep, take a shower, etc. So for me, the room was perfect. If you like to stay in the room and watch tv, this is not the hotel for you, as they do have small tvs in the room. The hotel is also located about 2 min walk from a metro station so you can go to other locations of santiago very easily. Matter of fact, i walked from this hotel to bellavista and that was a 40 min walk and it was midnite when i did this, so is also safe---at least it was for me.

If youre the type of traveler lookign for extra frills, this is not the place for you, for sure.
