We had a great stay at Arturo's! The apartment had everything we needed for our weeklong stay in Santiago. In fact, its probably one of the most well appointed AirBNBs we have stayed in.
Despite being on the first floor, the apartment is near the rear of the building and not the street. Therefore it is nice and quiet. The balcony door opens to the interior courtyard.
The wifi was blazing fast, perfect for video conference if needed and having Netflix was a nice touch to watch some movies on the large TV.
The shower is nice and hot and has great pressure, the clothes washing machine works well.
There are several good restaurants in the area (Indian, Peruvian, Thai) and a supermarket is only a couple of blocks away. It's about a 15 minute walk to Lastarria.
Would definitely recommend!
