In Canada, real estate agents say that the three most important qualities are "Location, location, location." This apartment has all three! It is so close to wonderful places to walk and only two blocks to a metro station to take you anywhere in the city. You will LOVE the neighbourhood so close to beautiful plazas and pedestrian streets!
When you first arrive you might be surprised at how small the apartment is, but think of it as COMPACT and packed full of everything you will need. We had no problem having enough space for our two large suitcases and our backpacks. The table is perfect for meals or computer work. (The Wifi is good and fast by the way.) The kitchen and bathroom had all we needed. On a clear day there is a lovely view of the Andes from this 21st floor apartment.
It was handy having a laundry room and gym in the apartment complex. There are lovely public areas on the top floor (25) but we didn't use them. There is a good grocery store just a block away and a small store ten steps away if you're craving a sweet or something.
Everybody in the building is very friendly and helpful. Patricia and her Mother (who greeted us and introduced us to the apartment) were excellent at responding to any and all of our requests. The building is secure with metal gates that you must "buzz" through with your key and a front desk person in the lobby who was able to answer all our questions (in my broken Spanish).
We would recommend this apartment when you come to Santiago!
