We stayed here for 6 1/2 weeks and loved it! It was centrally located to a lot of great restaurants, metro stations, museums, groceries, etc. The internet and wifi were fast and we had very few interruptions. I was working and taking video calls, which worked out fine. The kitchen is small but quite functional, and pretty well stocked. This unit is on the 15th floor and has a view of the Santa Lucia Hill park. There is a Lider Express grocery store on the ground floor. There is a laundry facility in the building, but also a small washer/dryer unit in the room that we used quite a bit. There is a pool and fitness center in the building, which were locked and by appointment only. We did not attempt to use these. The unit has a small patio, which is too small for a chair but nice nevertheless.
We really enjoyed our stay here and would definitely come back! It was the perfect spot to come home to after exploring Santiago!
