The apartment is exactly how it looks like in the pictures. It's small but it has all one needs to spend a few days in Santiago.
It's very well located, two blocks away from "D" exit of metro Santa Ana.
Alvaro was polite and gave us all the information about the surroundings and things to do and see in Santiago. He also was flexible with the checkout time, as he didn't have guests coming the day we left, which we appreciated very much.
The courtesy wine was very appreciated, the shower had very hot water and with good pressure and the bed was comfortable and warm.

To improve:
1 - I had asked for directions on how to get to the apartament by public transportation, and Alvaro only recommended the transfers which costed $10/person (against $2 for public). These dollars make a difference on longterm travel. We had to figure it out by ourselves and it would have been easier having previous instructions.
2 - When we arrived at around 9:30pm we were very tired from the trip, and one of our 6 small lugagges fell on the floor, it would have been a nice gesture from Alvaro to give us a hand with that, but he didn't make the move.. We do understand no one is obliged to that, but it would have been a nice gesture to help us instead of just standing there looking at us.

Overall, it was a good stay and I recommend for the location, good bed and shower, but be advised there's nothing fancy about the apartment as you can see in the pictures.
